Ballistics gel isn't a decent analogue for skin covered flesh. Skin has much higher tensile strength than muscle or fat. More importantly, I think the ballistics gel used here wasn't particularly dense (presumably for better jiggling).
Mostly because ballistics gel is meant for penetrative rather than blunt damage. There are way to make analogous human skin, but they aren’t really worth it for this experiment. Also ballistics gel gets soft quickly in the heat, which changes how it reacts to damage.
Awesome Video Louis! That was so much fun shooting the cannon off, that slow mo looked so nice! I honestly wasn't sure we'd be able to do enough damage at first but the burst disc fixed that I think :) Happy to be part of it, thanks.

Personal experience on this one, baseball size hail is frightening as hell, I was working as a janitor at the time a tornado passed over the school I was working at. It was dropping baseball sized hail and every time it hit the parking lot it sounded like a major league homerun going on.
I think your videos can be longer. I want to see how you set the air cannon to terminal velocity, or how you research the size of natural hailstones.

This is something I needed to know living in Texas. Considering how the weather has been so far this year would not be surprised to see the biggest hail ever
For reference, 1" hail diameter (size of quarters) is the new criterion for a severe thunderstorm based on impacts from hail. 2-inch hail is classified as "significant" by the Storm Prediction Center. And speaking of "Big Chungus", an 8.25-inch diameter "bowling ball" hailstone was dropped on the town of Vivian, South Dakota, from a very powerful supercell, making it the largest hailstone on record. This was recorded on July 22nd, 2010.
Hey ! I just wanted to say that your vids are getting better and better. You deserve more attention, you're starting to make the same awesome content as the top channels.
I sorta get the feeling that the pressure of your air cannon was a bit high. Any hail I've seen, no matter how hard the surface, normally bounces and is left interact. The fact that your synthetic hail is being obliterated on contact indicates they're probably hitting with a lot more force than real hail.
hey lois, the idea of this video was incredible, this damage may vary for differnet age groups, and the hail stons have material thats made of water and a couple of salts, and their shape is not sperical perfectly but a little rugged deformed. i say because they can impart very different forces at the same time. evenb a one inch hailstone can kill you, the gel was tthick, the momentum imparted by the small ones can even cause sever concusions, cause i saw a very real case in front off me, itt can literally rip of that flesh on your head. your effort here , his priceless. its lot fun to do mate. but hey i like this kinda stuff, soon i w ill be donating a lot of money here. thumbs up mate
i was riding a motorcycle at about 90kmph when it started hailling little piece a little bit smaller than a tic-tac. the time it took me to get off the highway and into a store i was later covered in spots of blood. the impact and water caused the skin to break and some blood to come out of each spot. it was like getting powerwashed. i was only in a t-shirt and shorts it was in the middle of summer and i decided that day to go to the dollar store buy some beach stuff for the next day. the cloud were starting to turn black and it happened very fast. the hail were covered in melted water as they came down.
@@sandrah4358 that healed pretty quick. it was very small hail, but the speed of the motorcycle added to the speed of the falling ice so that is that turned it for worst i think.
We had a hailstorm in Texas when I was younger that had around 4" hail. It destroyed the town and we had to live in a hotel for six months while our house was repaired.
If I recall correctly, and I read this in a book, Poland had Hail the size of grapefruit. Luckily no one died (I think it was also in the 1990's as well)
There was a hailstorm in Denver in 1990 with up to softball size hail...People were stranded on a ride at Six Flags when power failed due the storm. The storm was dropping just golf ball size hail in that area but still caused lots of injury. Nothing too serious but still scary. In Downtown Denver, just half a mile away to the East from the amusement park, the hail was softball size. That would have been absolute carnage had that part of the storm been just a half mile West. Yikes.
A few years back there was a freak hail storm and the hail was around 1-1.5 inches. A lot of cars were damaged and a local mall was destroyed because the hail broke the sky lights and flooded the mall so it was closed for almost the rest of the year. The hail was so damaging it chipped the pain on my mom's Jeep wrangler which had a coating on it to prevent the paint from chiping when she is off roading, we also found out that it was coming down sideways and had damaged the door to her jeep not just the hood and she had to have them both repaired and the dents pulled out
Wow, what the hail! [This joke was made by Jack Vance on May 5th, 2021. You may not use this joke without permission. My lawyers will be in contact regarding any violations.]
Terminal velocity for objects of a given density increase as they get bigger. I took an orange out the door skydiving once, and it fell almost perfectly relative to me. A grapefruit fell so fast I couldn't tuck up small enough to keep down with it, and also spun up and flew away from me at an angle with magnus lift. The danger from hailstones increases faster than their mass does because of the increased speed.
When I was seven in 1997 we had a terrible hail storm in Kansas. My dad, my brother, and myself were trapped in his truck a few blocks from home when it started. I don't know how we made it home because I just remember the visibility being nearly zero because of the size and amount of hail falling. We decided to run from the car to our house when we are parked out front and my brother got nailed in the head by chunk that was softball sized. Now it could've probably been closer to baseball size but the way I remember it being was gigantic, but I was seven. It gave him a concussion and he ended up having to go to the hospital after the storm had passed.
Love the video, I can see you put tons of work into this video BUT, I would have liked to see how close to terminal velocity those ice chunks were at. I believe I saw the chronograph set up, the weather geek in me wants to know exactly how close to irl this was. Again loved the video, I'll be back to check out more content.
I would guess they used the formulas for drag and the basic force equation to calculate the terminal velocity. They had a chronograph so they then used that to tune the velocity of the ice balls.
Interesting video but at the end of the day in your test which hails would kill? It just kinda seemed a little bit scuffed when it came to final conclusion. You could've found what force to the head would be fatal and at what speed do hail usually fall? Shooting the hail out of a cannon and not mentioning how fast they are going just seems like something you should mention. While you tested the hail you could have calculated the acceleration which i thought I saw some reading equipment Infront of the cannon and with that calculate the force of the hail. Keep it up!
I live in Texas and several years ago we got the worst hail storm I've ever seen. I didn't actually measure it but we had hail fall that's wasn't just bigger then my fist but my entire open hand. These things punched holes through not only our roof but the ceiling underneath it. After the storm was over you could see the sky from inside the house. Only time I've ever had to hide in the bathroom from a storm that wasn't producing tornados.
None of this is an accurate experiment unless you can prove hail falls from the sky at that speed. At this point it’s just shooting ice really fast, nothing makes it represent hail

your videos always have such exciting premises. for me personally, I would love more long-form content. I know that's not the most efficient nor the best performing format, but I would love to sit down and enjoy a 20+ minute video. keep it up.
@@jebbryant6522 if you push a piece of paper towards the flour you can push it faster than if you dropped it (it’s terminal velocity) So if you fired that ice down a skyscraper wouldn’t the ice slow during free fall, because it started at its terminal velocity Therefore without calculations the ice is going beyond its terminal velocity Therefore more damage than if it was a normal free fall from clouds
I’m interested to know how solid the hail was. All the hail I’ve seen especially the larger chunks aren’t the most solid things it feels like compressed shaved ice and has air bubbles inside
In Wyoming where I live last year we had 2” hail but 2 years ago we had 3/4” hail. It was scary it broke all the windows on the cars totaled all the vehicles except the mini van that we used to leave.
In arizona we had this really weird huge storm and on the highway it was hailing so hard everyone had to come to a complete stop and by the end my moms car was covered in hundreds of dents
I live in a place where we get hail every once and a while and it destroys everything in its path Edit: you also have to remember that there are thousands of these things, just like rain but scary
One time In Colorado while on a road trip there was a hail storm while we were driving and it cracked the windshield. Another time in my neighborhood in texas we had a hail storm that broke a few windows, and roofs.
Well smallest size would have to be in the .5in range. If you are staring right into the sky and a piece of hail has formed into a thin pointed shard and it goes right into the ocular cavity. But the odds would be astronomical of even getting a piece of hail at that size to form such a particular shape and fall right when you are looking uo
Another fun hail fact (or theory really) is the way hail grows in size. It's assumed it grows when it falls out of the storm and gets caught in the updraft of a storm. So it melts going down, and refreezes going up. Creating concentric growth rings as it adds mass. Its known as multiple trip theory. So the stronger the updraft, the bigger the hail!
I think there might be a couple problems with this. Your ice density is going to be higher than natural hail due to the fact that you are freezing them solid. Most hail grows sequentially within the updraft and accumulates air between the layers, that's why most hail is cloudy and opaque rather than clear like ice made at home. It also looks like your terminal velocity is a touch too high for smaller stones. I can tell you that most hail less than an inch in diameter will not dent metal unless its wind-driven. Terminal velocity on half-inch or nickle sized hail is around 40-50 mph. You add in horizontal wind components of 60 and 70 mph then you start getting higher velocities. Looks pretty good beyond that for your other tests. Ask any storm chasers and they will tell you 2.5+ inch hail will shatter windows with ease and leave nasty dents. Definitely don't want to be out in it without a helmet. The largest I have personally seen is 3.25 inch. Cool tests! Im a severe weather meteorologist for the US National Weather Service and have been storm chasing for 10 years.
The hailfall we had 2006 in Leipzig, Germany during the soccer word championship, was like 2 - 2,5 inch each and it massively destroyed peoples car windshields and also hit peolpes heads, but no one died. Only some in hospital as far as I know.
I’d be willing to bet that building g it up with multiple layers makes it stronger than the whole thing freezing at once. Not to mention, if there’s any kind of dust or whatnot in the air, it’s going to make it almost like pykrete.
Hi! Weather technician here. Typically when we issue warnings for hail we consider anything greater than .25in to be moderate and .50-.75in and up to be severe criteria. So you started with something thats already pretty scary to me!
It's worth noting that hail does not just fall once.
Many hail pieces would hit you, so is more dangerous.

Not stupid but they do say at one point that they used enough psi to reach terminal velocity
@@jebbryant6522 if you push a piece of paper towards the flour you can push it faster than if you dropped it (it’s terminal velocity)
So if you fired that ice down a skyscraper wouldn’t the ice slow during free fall, because it started at its terminal velocity
Therefore without calculations the ice is going beyond its terminal velocity
Therefore more damage than if it was a normal free fall from clouds
I’m interested to know how solid the hail was. All the hail I’ve seen especially the larger chunks aren’t the most solid things it feels like compressed shaved ice and has air bubbles inside
Hi Louis welcome back!!!
Thank you!!
Everyone: Hail is scary
Me Who Lives in a tropical country: im 4 paralel universes ahead of you
That moment when Louis uploads on ur birthday
Happy birthday!
@@Weisz thanks bro
Great production value Louis, like a clip from myth busters
Especially because of that G-force sticker
NOW THIS IS THE INFORMATION I NEEDED
In Wyoming where I live last year we had 2” hail but 2 years ago we had 3/4” hail.
It was scary it broke all the windows on the cars totaled all the vehicles except the mini van that we used to leave.
*Now this is content.*
In arizona we had this really weird huge storm and on the highway it was hailing so hard everyone had to come to a complete stop and by the end my moms car was covered in hundreds of dents
this dude is walmart micheal reeves in a good way.
i’m honored
Really great content, keep it up bro 🔥🔥
I live in a place where we get hail every once and a while and it destroys everything in its path
Edit: you also have to remember that there are thousands of these things, just like rain but scary
One time In Colorado while on a road trip there was a hail storm while we were driving and it cracked the windshield. Another time in my neighborhood in texas we had a hail storm that broke a few windows, and roofs.
It’s not what size, it’s what’s the smallest size
Drops ice burg on head
Well smallest size would have to be in the .5in range. If you are staring right into the sky and a piece of hail has formed into a thin pointed shard and it goes right into the ocular cavity. But the odds would be astronomical of even getting a piece of hail at that size to form such a particular shape and fall right when you are looking uo
Next vid: What size Hail will break a Nokia phone?
This reminds me of that one movie where a hail fell onto a car and it was the size of a table
THERE’S MORE BEHIND THE SCENES?!? You showed us so much! Yup, I’m definitely signing up for the Patreon.
10:20 just walk it off
GG EZ
Another fun hail fact (or theory really) is the way hail grows in size. It's assumed it grows when it falls out of the storm and gets caught in the updraft of a storm. So it melts going down, and refreezes going up. Creating concentric growth rings as it adds mass. Its known as multiple trip theory. So the stronger the updraft, the bigger the hail!
Nobody asked but everyone cared
I think there might be a couple problems with this. Your ice density is going to be higher than natural hail due to the fact that you are freezing them solid. Most hail grows sequentially within the updraft and accumulates air between the layers, that's why most hail is cloudy and opaque rather than clear like ice made at home. It also looks like your terminal velocity is a touch too high for smaller stones. I can tell you that most hail less than an inch in diameter will not dent metal unless its wind-driven. Terminal velocity on half-inch or nickle sized hail is around 40-50 mph. You add in horizontal wind components of 60 and 70 mph then you start getting higher velocities. Looks pretty good beyond that for your other tests. Ask any storm chasers and they will tell you 2.5+ inch hail will shatter windows with ease and leave nasty dents. Definitely don't want to be out in it without a helmet. The largest I have personally seen is 3.25 inch. Cool tests! Im a severe weather meteorologist for the US National Weather Service and have been storm chasing for 10 years.
I think that's a bit faster then terminal velocity for those smaller hail stones. Cool video! The larger hail velocity seemed more accurate :)
The hailfall we had 2006 in Leipzig, Germany during the soccer word championship, was like 2 - 2,5 inch each and it massively destroyed peoples car windshields and also hit peolpes heads, but no one died. Only some in hospital as far as I know.
I’d be willing to bet that building g it up with multiple layers makes it stronger than the whole thing freezing at once. Not to mention, if there’s any kind of dust or whatnot in the air, it’s going to make it almost like pykrete.
Nice! I forgot you told me about this video, you finally made it, lookin forward to finishing the video
We got 4 inch hail here in Roundup Montana a couple years ago
7:46 SUTUTUTUTUTUTUTU same as a turbo when u send the boost back through the compressor wheel lmao
I, and 82K people just found a magnificent channel, no doubt.
I'll turn on the bell to see anything, from hail skull cracking to icicle killing!
This show is like a new age mythbusters, I love it.
