Hello Ben, I really love your show and I got a question for you on the pressure pot. Do you introduce pressure or do you take it out?
@@BubaLabinski223 Hi Mate, I add pressure
I would really love if u done a project with the original star trek enterprise
@@BensWorx thank you Mr. Ben and I love your show and you’re very talented especially with that lathe
Ever consider decompressing it very slowly to allow the epoxy to withhold the pressure of the air bubble more equally?
It would be interesting to see what would happen if you used bubble wrap. Lots of tiny fractures maybe?
Yeah 🤔
@@BensWorx hopefully you consider this idea for a video I would really love to see that. Bubble wrap is thin so should pop very easily from the heat of the resin and release the air.
Yes!! Absolutely, I would love to see this experiment!
@@robertfuchs2227and if wrapped around a cylinder stuck straight up in the center of the resin maybe we could see a 360 effect of mini explosions going in all directions. Would be a neat visual assuming the bubble wrap works
You could inject coloured liquid or glitter into some of the bubbles to see if you get lots of mini colour explosions!
A couple of things happened with the glitter bag. The pressure pushed the air out of the bag and the heat from the reaction melted the welded seam. To replicate you would have to seal the zipper making the fracture come through the weaker side weld of the bag. To seal the zipper run a lighter across the female part of the zipper. That will normally seal the zipper tight to where you can't open it. By not doing this you run the risk of air escaping through the zipper again. I made Ziploc bags for 35 years and learned a few tricks.
what is the female part of the zipper?
@@ellaenchanted2399 there is an inner and a outer of the zipper. The inner is the male and the outer is the female
@@theboz1419 interesting. I would have assumed it would be the opposite
The air definitely escaped through the crack on the second one, as indicated by the glitter near the top. If glitter made it that far up, air surely did as well.
My thoughts were to add a few drops of dye in the baggie... See if there's a color explosion!
I was thinking the same thing about adding some dye. Lol😁
I was thinking pigment powder
Of all things you have cast the air was brilliant, original and probably the only air cast ever, so glad to be here witnessing the fracture phenomena. Thank you 👏👏👏
Thanks Alison 😊
I always love your cheerful calmness in these videos. Almost like a young Mr. Rogers taking up resin crafting.
Now take the first with the great fracture place it in a slightly larger container and add a colored resin and vacuumed the air out and try to suck the resin into the fracture, I think that could be cool to see
I can watch these kind of random experiments all day
I REALLY WANT A COUPLE OF YOUR STAR WARS BOTTLES FAM STAY SAFE AND STAY BLESSED YALL
The pressure is compressing the air in the bag to a smaller “compressed” volume around the glitter in the bottom of the bag. When the resin cures and the pot is decompressed the air volume expands and causes the fracture but the fracture is too thin to carry a larger amount of glitter.
Try putting the small glitter/air filled bag glued to the top on the inside a larger bag filled with air.
Both will compress but the glitter at the bottom of the small bag will be at the top and will decompress at the same rate as the air in the bigger bag but by being at the top more May escape
Also, it looked like the glitter bag failed prematurely at the seam. This released a small amount of air at a time. If you watch pot cam closely, you can see a straw and bubble form very early on and, the bag deflate.
I recommend you reenforce the bag seams with scotch tape and UV resin. Or, utilize a pass through into your pot to set up an air injection system. You should be able to do this with one of the turkey injector needles or something similar. Just coat the needle, inside and out, with mold release so your can remove it.
I think the videos I love and remember the most are the ones with a burning question or some science that needs to be tested. Experiments are always fun to watch
The glitter provided space for the air to compress into. The bag seal was able to hold against the air pressure. Therefore the air remained in the bag.
Looks like a wave... Pretty
Puff goes the air-in-the-bag!
I love this channel. Weighing scales, resin and zip bags. Just like being at a friends house. Great work
Don't forget the powder!
That was fun, thank you Ben! I love the detail of the purple straw to blow air into the bag with purple glitter.
You're the Ben Kenobi of Epoxy Resin Experiments 😎👍
You had less air in the glitter one than in the no-glitter. So you had less force of escaping the air. To calculate - the explosion, calculate the amount of air on the first page and use a larger bag and calculate its volume minus the volume of the glitter. That is simple math to figure the volume,
Was thinking the same thing
Agreed. I was also thinking less, and much finer glitter plus larger bag.
I think if you used a very fine powered glitter or coloring it would show more in the fracture not just at the top where some of the glitter ended up this time. And try one with part air and glitter with some water or liquid coloring in the bag. Oh and maybe try one with a much thicker bag, maybe it would not melt as quickly. Just a thought, awesome video as always!!
I wondered if the resin heat would melt the plastic bag so it’s neat to see how the 2 different versions of the experiment worked out. As always thanks for a great video, Ben!
Thanks Kara 😊
If you want a coloured explosion, you could maybe try using two bags: one inside the other.
Fill the bigger bag with the material that you want exploded, devoid of air (e.g coloured water or water mixed with glitter or sand) and put a smaller bag filled with air inside the bigger bag.
Then the smaller bag would explode and send the surrounding material flying.
You could also try making bubbles of air out of plasticine. They might explode like popcorn in the resin.
I think the problem with the second one was that the glitter took up too much volume and thus there wasn't enough air under pressure and warmed up from the setting resin to push out and rise up when the plastic baggy melted.
At the end of the video, the one on the right looks like either an unusual butterfly, or an insect walking along on a branch. Absolutely fantastic.
I think that the melting plastic bag also melted the plastic glitter a bit too, thus preventing more from escaping. Most glitter is made of plastic.
Put glow resin in the bag and under pressure so it can highlight the fracture 🎉❤
It was VERY cool to watch on potcam as the bag with the glitter compressed. The "movie" is better than the final result!
I watch this channel for the experiments.
(And the pot cam, lol. And your brilliant pieces.)
Very cool experiment, Ben!!! ❤️❤️❤️👍🏻👍🏻👍🏻
I recently realized that the Smithsonian Air & Space Museum in Virginia, Udvar-Hazy, has the original starship Enterprise filming model in restoration! That museum is only about an hour from my home, we can't wait for it to go back on display!!!!!
Oh, what a neat experiment! I've read many of the comments, and agree that you've got a great jumping off point here. Using what some might call a flaw to deliberately manipulate a material is something very Bob Ross. Please explore this idea more!
Yes! That was really cool. I like experiments!
Use glow in the dark glitter! Might be cool. Good vid!
You should look at camera housing for deep sea diving/exploring they are made to withstand extreme pressure like you use in the pot
Great idea for an experiment. I'd like to see two things - one, using bubble wrap, but with several different types of wrap. Some have larger bubble pockets, so it'd be cool to see the different effects they produce.
Two, using different coloured gases instead of just air. Unfortunately, this might be impractical, because most of these gases are toxic and would need very careful handling. Fluorine is yellow and chlorine is green (I think), but might be nice to see what happens when encased in resin.
Theory:
As the air was at the top, and the surface with the least support was the top, the air escaped with minimal mixing of the air and glitter.
Idea:
In a small cup seal a bag of glitter in resin with part of the plastic bag reaching out the top. Once it's out if the pressure pot, use UV resin to cure another bag to the opening front the first cure.
Cure a base in a second, larger cup.
Remove the resin from the first cup and suspend it upside down in the second cup. Fill the second cup with resin to cover the full air bag and just a slight amount of the first resin. Pressure pot it and see how it cracks.
Also: can you change out the fittings on the pressure pot to high flow fittings? A faster change in pressure should create more violent cracking.
I think you should try with powdered paint next time. Since it has a much smaller granule size, the escaping air will probably push a lot more of it through the fracture and give it color.
Milk paint should do the trick.
So the bag collapsed. Imploded as it were. That’s very interesting. Wasn’t a big explosion but it was keen. I have to say this is fun to watch.
The air compressed under pressure (the whole reason for using the pressure pot is to compress air bubbles.) Then when you released the pressure, you can see the "poof" as the air expanded and came out the fracture at the top of the cup.
I love watch'n your experiments! This was neat!
Thanks Stacey
Very interesting! This could be a breakthrough to something new. Thanks
The pressure pot reduces the volume in the bag and the explosion occurs when you release the pressure and the air in the bag re expands so an idea is to set up as normal but instead of using pressure pot leave it for the 40ish minutes in normal pressure and then pull a vacuum on it to see if you will get a better/same/worse result
That’s not an air fracture around the Enterprise. It’s a tear in the space-time continuum!
2 projects in one video! Thanks, Ben!
The air in the bag was compressed, when the resin was setting it created an enormous amount of heat, the air absorbed this heat, and as the resin wasn't fully cured yet at the 40-minute mark, the release of pressure caused the super-heated air to expand and find the easiest way out of the resin. The heated air had a larger volume than the cooler air at the beginning, that is why the fracture happened.
Nice experiment! Try with a glass vial or a rigid plastic tube next.
i don't have to cook because of all the delicious leftovers AND I got 2 (TWO!) pot cams. It's been a great Friday!
I think the air inside the bag got compressed to the point that it isn't visible. I think it might be worth doing it with something that isn't heat sensitive but will break from the pressure.
I swear I just be straight up vibing to the potcam music xD
Most likely the air in the bag has moisture in it which created a steam pocket from the heat of the curing process. While under pressure in the pot it was contained. Once there was no exterior pressure the steam was able to escape, causing the fracture.
I hope one of the resin manufacturers see this and can explain what they think is happening.
I feel like this bag trick would have been perfect for the water videos
This makes wonder about casting with a laundry detergent gel pod? I mean, the outer casing is meant to dissolve in the wash, but I don't know if the resin would have the same effect; and I would hope the the detergent gels wouldn't interact with the resin. But I would think there'd be at least some air trapped in the pods, to create a fissure and maybe push the different colored detergent gels in different directions?
Try doing it the way you do the trapped water. Let the resin get to an almost cured state, blow an air bubble in it, then put it in the pressure pot to finish
That was really cool! Disappointing that there was no glitter explosion, but still really cool!
Thanks Lisa
Try water in the bag with the glitter. as the bag melts it releases the glitter and causes a mini explosion? like the ice and stuff did? its a thought.
Pressure compresses the air, so it takes up less space. Even if bag didn’t melt, releasing pressure will cause air to return to original size, pressing out with the same force it was compressed, about 60 psi (not positive about the units on your pressure pot). Anyway, that pressure causes the resin to fail. You could test one in pressure, one in vacuum, and one just in standard air and compare results
Hello from Wisconsin, USA. Love watching your videos, and want to share a few suggestions I think would be pretty neat.
1) fake rose or flower of some kind. 🌹
2) a fossil or sea shell 🐚
3) glow in the dark star or planet ✨🪐
4) toy animals 🦓🐷🐕🐮
5) marbles
Before I say this know I know NOTHING about resin. But watch you and Peter browns channel. And some others. Would it be interesting to try pressure and vacuum pot to compare? I’m not even half way through. But interested nine the less!
crazy idea time, get a small container then cast resin in it like normal, on the band saw cut the top for a lid, then using the lathe create a thin walled well inside it, so you are basically making a container. Invert it so the lid is on the bottom, now for the crazy part using the UV resin glue the lid back on and drill out a hole. Put in a bike Schrader valve and glue that in. Then get a piece of burl and make a wooden base with a hole to cover the Schrader valve. Then pump in around 5-10 psi of air into the valve (you don't want it exploding in your face). Then place it into a larger pot and pour in your resin. Put that inside the pot and do as normal. It should technically explode inside the pot.
When you add pressure you squeeze down the air in the bag the same way you do the tiny bubbles. When you release the pressure because there's so much more air it expands back to its original volume cracking the resin. That's my theory anyway.
It would be interesting if you put colored slow cure resin in bag and clear fast cure resin around it and see if it will mix when bag melts and how it spreads when you induce the fracture.
That was pretty neat, Ben!
Thanks Mate
Hi Ben, cool experiment 😎. I think you might need a bigger bag to allow for the glitter and to have enough of air to go puff 😮😂. It could work. Hope you are all doing OK. Take care. 💌🙏☘💗
I would suggest using a colored smoke/gas to fill the baggie. That might colorize the fracture. Someone else was also worried about the glitter melting and I thought "that would be awesome to see!" If you could cut up some colored baggies into ribbon or glitter sized pieces they might twist and contort further while curing, that would make a good potcam.
Always so cool to watch your video!
Very creative piece of work ❤
Thankyou
This was so cool to watch. I wonder if having glitter in the resin would make a interesting look when the fracture happens 🤔
Love this! The colorless one is really pretty imho 💕
I wonder if you tried a glass vial. Shouldn't melt, but the pressure release/difference could be the more explosion your looking for.
Love your experiments!
Hello Michele
Cool thanks for sharing this video... I look forward to seeing any future glitter 💥... I hope that you and your family enjoy the holiday season.
Thanks Susan, you too!
Still loved the experiment, maybe try a lil bigger bag so it'll hold more air. Lol that means bigger container bigger glitter boom 🤣
I feel like the glitter bag needs more air in it, that way when it compresses, there would be a greater amount of outward force when the pressure is released.
An idea might be to introduce a bunch of air into the resin as it starts to cure so it holds on to the air better, and then throw that into the pressure pot. try to get some large bubbles. maybe this is possible?
You might get a better glitter explosion if you use nail art powdered glitter
I became concerned that the glitter might melt along with the plastic bag, but the glitter seemed to be moving around okay, so maybe it was just because there was less air in that pocket than the other one (the glitter took up too much space)? Maybe try it with a shimmer dust next time? Shimmer dust is much finer and means you would need a lot less of it, so there would be more room for air.
Maybe use colored plastic bags that have been cut into ribbons or glitter size pieces just so they can melt when the resin cures?🤔
Should try helium. Compresses as dense as air but will expand way more. Wonder if that will cause more of a pop
Ben's Science Works 😆
Using a vacuum tank could yeld a better result.
For the cost of another camera, you could put a pyrex or acrylic window in the base of the tank, then lay it on it's side. Only needs to be 2inches across or round. Lighting - LEDs.
;)
That was cool watching the hot air escape when the pressure was released
That was a great experiment! Was so hoping for a glitter bomb. Oh well maybe next time! Great job Ben!
Thanks Linda 😊
Hi Ben. Fun as always!!
Thanks Ellis 😊
Oh I would love to see you cast gallium or Indium. They are safer low melting point metals and I bet they would make something cool as they would melt as the resin cures. Bismuth would be really cool, but I don't think any resin get hot enough to melt it, even with the low melting point.
in the pressure pot, the much higher pressure compresses the air inside the bag, so it takes up a lot less space. when you release the air, the pressure inside the pot drops and the air in the resin wants to expand back to the amount of space it took up before you added the air to the pressure pot, but there's not enough room for it. the air pushes really hard on the resin, so if it's not fully cured, then the air can push its way out of the resin by cracking through it until it either reaches the outside or has made enough space in the fractures for the air to expand to its previous volume.
Such a cool experiment!!!
Thanks Melissa
Hey Ben
Looking forward to watch more, as you continue this air experiment.
Take care
Thanks Tim
Cool experiment. Now I can’t wait to see what you do with these!!
Here's an idea you might like, what if you partially filled a water balloon up with coloured resin and squeezed the balloon before tying it so you could pop the balloon in the resin before pulling the remains of the balloon back out using thread?
Dunno if the same could be done by just injecting the colour in but maybe could do a comparison?
Well that was a fun one Ben
Thanks Sandy
Might try putting smoke in the bag!
I think the bag with the glitter leaked air when you put the pressure in the pot, so when you removed the pressure it didn't explode like it did before
That sill looked awesome though
Thanks Beth 😊
Awesome video Ben! Always a great feeling getting that notification
Thanks Josh
I think you should try to make a clear lightbulb explode in the cast. Lightbulbs have a partial vacuum inside so maybe when it breaks under the pressure the resin will be pulled inside instead of exploding out into a fracture
That was interesting. The reactions of the different types was just awesome
Ben I have an idea. Not sure if it will work or if you want to waste the time doing it. Maybe put ink in the resin and a different color in the hardener. Then pour them in the mold like you do before mixing them together and just put it in the pot? Maybe it would make a cool design?
It has nothing to do with "escaping" air. What happens is that you compress the air while it is curing and then when you release the pressure, resin has less support from the outside, so the air that is inside able to overcome the pressure from the resin as it expands to its original volume. If the plastic melts, the air may be released, which would result in less air compressed and it being less explosive. Also, just having glitter in the bag means that there is less air, so less force is exerted by the trapped air.
Nice idea Ben I wonder if the glitter was too heavy and if it would work better with just mica powder? Also is there any way you could add more pressure to the bag so it's fit to burst straight away I think a slightly bigger bag and a quick burst from the air hose might help plus it would need more resin which in turn would create a deeper pour and more heat so even more chance of a fracture
Would be really cool looking if it were filled with like a blue colored smoke.
I think you should do the glitter bag experiment again, but let it cure on the bench. Let just the heat melt plastic bag. Results might be different than being under pressure. Maybe try this with a resin powder also. Great video!
Thanks!
I must admit, I didn't expect them to turn out that pretty. They look really nice 🙂
Thankyou
