cellohane was popular before petroleum plastics.
Another one:
Mix glycerol and citric acid at 1-1 molar ratio without any water (the correct ratio is _very_ important).
If you cook/bake it slightly above 100C (effectively removing the extra water coming from the cross linking esterification reaction)
you can get hard foam, or thin hard coatings. For hard coatings you need to start below 100C and very slowly increase the temp to prevent foaming (the entire process can last for a day).
The resulting polymer is highly biodegradable, but if it is was baked long enough it can resist water for a _few_ minutes.
(NaOH or KOH or even sodium carbonate can destroy the polymer it if boiled in water)
I think controlling the drying would be a way to improve.
Maybe peeling the potatoes too as there is little starch in the pees and maybe the cellulose in the peels affects the polymerization?
Or maybe it acts like a nucleation site helping the glucose form cellulose.
My thought is somehow making it into a 2 part anhydrous resin because a lot of the volume is water causing it to shrink.
Very entertaining presented! 👍
Nice and simple - well suited for childrens to discover home science, too! My daughter and me like such stuff. 😊🙂
10:40 R.I.P. bio plastic 😉
Awesome video! Didn't know it was so easy. Another video exploring additives would be very interesting. Keep up the good work!
Great videos! This channel is gonna blow up like me trying to do chemistry.
And I like that you also show possible side experiments (here: Oobleck).
Mum, can we get some Lego?
We've got Lego at home!
😂😂😂
One thing, tho it may have added a few steps, the material you filter out right at the first is largely cellulose fibers, which would work similarly to starch, but have more long chains and some cross bridge chains.
"You can use corn starch, potato starch or wheat flour, but I will go with potato starch just because potatoes are the best meme"
You can't argue with that logic! 😄
Amazing work! I love your videos, you make me learn so much, you're overly underrated I wish you had more visibility!
Thank you! I'm glad that you can learn something from my videos :)
pretty cool!
You had me at potato ASMR😂
Great work¡
You have a new sub, good man.
Great video. I wonder if there are some nontoxic processes to cure it into a quite hard plastic that can be used and casted into little jars for storing things. Maybe it could also be treated with those water proof sprays in order to hold wet things in it (not for human consumption of course). Maybe curing it in the oven would work with a higher concentration of Vinegar.
without the glycerine it would form a hard plastic I think
Nice. can you make a video for a beginning lab? I have all the basic glassware, just looking for some experiments to do. Single replacement, double displacement, synthesis and other things that are simple
Well you can try turning eggshells into calcium carbonate crystals, then you can use HCl to turn them into Calcium chloride. There's like TONS of simple experiments like this on the internet, I'll point you to a few different sources: ElementalMaker, NileRed, Cody's Lab, Extractions&Ire, Explosions&Fire, learn using these ressources! And then if you wanna learn the theory of chemistry there's Khan Academy courses for free which are AWESOME and super simple to follow along
Hi, thanks for your video, nice work. I would like to do some artwork with bioplastic but I don’t know if I can get it to dry to a 5mm thick sheet, I assume it would still have a malleable behaviour but I would like it to be harder, do you know of a way? I have coffee mugs that say they are made of cornstarch but how do they get it to be that hard?
Hi, its me again. The recipe actually works ! I am now experimenting but i will make a video and i will make sure to credit you for the recipe in the video !
Hi, I am glad that the recipe worked for you! Also that's very kind of you to credit my recipe :)
Would it be possible to make filament for a 3D printer.. I think that would make for an awesome video,, and awesome in general.
The potato plastic unfortunately cannot be reheated, so it can't be made into a filament, however i have an idea of making PLA plastic from sugar in the future.
@@Amateur.Chemistry Not everything 3D printed needs to have thermoplastic properties, or be a filament. FDM can use many different materials. If I had an auger/hopper feed for my printer [and the space to set it up :( ] I would totally be playing with this. Oooh, I still have chitosan from when I was trying to make biodegradable plastic fish baits. 🧠⚙⚙
@@tykokavaak5784 there is also the slow drying times to worry about, I have also heard it is rather inconsistent in texture and would get clogged in nozzle too easily
I wish to see someone making it water-resistant. I did some research and this could be interesting:
Reinforcement with natural additives: Incorporating natural additives like waxes, oils, or resins into the bioplastic formulation can help improve its water resistance. These additives create a hydrophobic barrier, reducing water permeability. Examples include beeswax, carnauba wax, or natural oils such as palm oil or soybean oil.
High quality cold pressed linseed oil as a base layer could work. Good quality linseed oil or flax seed oil is used all the time for making food grade surfaces in wood working already since it’s a nontoxic drying oil. Putting it in the oven to cure the linseed oil @150f for 30min intervals over and over again till it’s dry and doing two coats of that I think would work well. I do oil painting and when I am feeling impatient I try to dry the paintings in the oven and it works well if I can’t use a quick drying medium like galkyd lite or liquin. Using a quick drying medium like liquin or galkyd lite would be good for curing the linseed oil quickly for a cup at room temp as an additive to the linseed oil coating but they are pretty toxic. It would avoid putting a linseed oil coated plastic in the oven from warping but it wouldn’t be food safe. I already have everything and it’d be simple enough with the methods in this video as long as I can get the plastic hard enough before hand and water free so I might try it.
I wrote too much my bad.
@@AssistantLeaflet That is indeed very interesting. I wonder why linseed oil is so different from other oils. Maybe it acts more like a resin? I just did research on natural resin and that could also work.
Good for food storage .... how long till it rots if left in cupboard in sealed container, or does it need to be refrigeratored
great experiment! What can be used instead of glycerine? And how to make it harder?
Thanks! If you want to make it harder you must use less glycerin and more starch. When it comes to replacing glycerin i dont know what else would work that well.
Something a lot of people don't really seem to consider is that one of the big problems with plastic is not just that it hangs around for a long time, but when it does break down into nanoplastics and microplastics, it ends up in the food web, and can cause all sorts of unforseen negative effects. If you have a plastic that breaks down into the same things as a potato, it's much less bad news if those by-products end up in an animal. Much better to end up with potato in your bloodstream, rather than polyvinylchloride.
@Amateur Chemistry What about converting polystyrene into more harmless benzoic acid? I think it is a good idea to try to do some recycling with that nasty plastic.
How about making cellulose base bioplastic?
you could probably add some sugar to the mix to purposely make it sweeter, so you could make a plastic candy kinda thing.
you'd have to dissolve it though to prevent it from being gritty
Its a nice try. I have a question. As I saw it is dissolving in water. How can we improve it in to a manner that we can pack the watery things inside like in normal plastic?
thanks
Ah, the "hurrdurr six hundos" music
Can you tell what kinda mixture to make plastic Hard or can be be say turn be pcp plastic
forbidden kisiel XD
This would be perfect for a little kids science fair project. Parents write this down😂.
Is the last product is can be Remelted please answer.
hi. great video! i have a question...apart from water, what enemies does this plastic have? do contact with metals ...aluminium for example..or salts.. etc cause any kind of adverse results?
Thanks! This plastic doesn't have avy reactions with metals and probably salts too, but since it is made out of starch some kinds of mold can probably eat it when it is wet.
@@Amateur.Chemistry cool. and thanks. i think i can genuinely make use of this process. but i wouldn't have even considered it until i saw your vid. Keep well, and keep going! :)
Technically this can be plastic but will it get mold(fungus)? It would be nice to test a rigid type vs a rubbery type and see their strengths, how durable, if any are resistant to water and at what temperature limits. I can see myself making a mold with this if I knew a recipe that would resist mold (fungus) at least
How do u make pla or poly-lactide
How many days will it take to do this job ?
Can you vulcanize it?
Wondering if any foods use this process without being aware its a plastic
8:10 at this point it’s children’s glue and can also be used as wallpaper glue
2:32 Pov: you are making school launches
this is almost the recipe for Turkish delights , they use tartar as the acid
Turn potatos into butyric acid [through anaerobic fermentation]. Hundreds of liters of butyric acid and other subtsances were made from potatos in the near past. I just wish someone on TH-cam recreate it small scale

You turned potatoes into plastic, but can you turn plastic into potatoes?!?!?
You can probably us antifreeze as a glycerin source
any solution to replace glycerin with? can we use honey?
Maybe, although honey and glycerin are two completly different substances

Question, does also flower starch work ?
Probably, altrough i havent tested it.
@@Amateur.Chemistry oh, well then, I will test it my self and probably make a video. Thanks for the response. Also, great chanel ! You, diserve my sub.
Thanks! Your channel is also great :)
@@Amateur.Chemistry thankyou so much
i just made some, it does work, although it makes the plastic a bit more yellow for some reason. might just be my flour, but it was like a cocoa butter color.
What about to do some wood or milk plastic😏
Watching potato grind makes my hands hurt.
Amazing job well done how are you
Thanks! I am good :)
@@Amateur.Chemistry i can't wait to try it and what does it taste like and what does it do to you
All plant fiber that is so important to controlling cholesterol and sugar levels are cellulose plastic. They are not making bioplastic they are just harvesting it.
=AHA,THAT'S A TIDE CAPSULE CHALLENGE BASICALLY AS FAR AS I KNOW
........AND YEAH,THAT "PLASTIC" IS ACTUALLY PRETTY MUCH COMMON DISH AND NOTHING SPECIAL......WHEN I'M LIKE TOO MUCH STRESSED I'M MAKING A HUGE BOWL OF IT AND EAT FOR SEVERAL DAYS......OF COURSE IT'S VERY SWEET BERRY FLAVORED
The cells will rupture if you freeze the potatoes
Use wax paper
I mean, it's interesting and all but not really useful for anything, right?
I think the biggest problem is that we want something relatively biodegradable but also something water resistant, more like wax..
Turning plastic into potatoes would be far more useful .
نريد بلاستك مفيد للاستعمال لا يذوب في الماء وملاحضة نريد فيديوهات من مواد متوفره في المنزل او كيفيه صنعها من مواد في المنزل لان يصعب الحصول على المكونات الكيميائية على سبيل المثال حامض الهيدروكلوريك وغيره We want plastic that is useful for use and does not dissolve in water. Note, we want videos of materials available at home or how to make them from materials at home because it is difficult to obtain chemical components, for example hydrochloric acid and others.

Don't bury acidic things in the ground
Uff. Vowel pronunciation is very difficult to understand.
6:35 carbon is used to harden iron and its also the base of our biology whats ur point duh . jk xd
grinder anyone, or a ball mill, or a potato mill, what interference, excuses
milk + vinegar = plastic
synthesize that glycerol/-ine yourself
if you buy all the ingredients then you could directly buy the plastic as well, no need to complicate that process
