Acetone and Styrofoam!

video Acetone and Styrofoam!
Hi guys! I hope you enjoy this science experiment.

You need:
-Acetone
-Styrofoam
-A metal or glass container

Safety advisory:

Acetone fumes are flammable. Only do this in a well-ventialted area. Always wear safety glasses, and wash your hands well after handling acetone.

Have fun!

And you have made napalm!
Chikpeas Brother (author)  kminnie6 months ago

Effectively, yes. I believe napalm is made with gasoline though.

Well technically speaking anything that is a gelled Incendiary... The first Naplam was Actually made up of Naphthenic Acid and Palmitate, hence it's name. But more commonly now napalm is made with petroluem products like Gasoline...

Good instructable BTW!

Oh, that makes sense. Do you know what mechanism a flamethrower emplys to propel it?

Thank you!

Gasoline melts styrofoam, too.

Chikpeas Brother (author)  rimar20006 months ago

True. I just went with acetone since it's more readily available.

WOW, here in Argentina it is on the contrary. Acetone is named "drug precursor" and then its market is controlled. You must declare the use you will make of it when buying.

By the way, the solution styrofoam-gasoline does not serve as adhesive. What is the case with styrofoam-acetone?

Chikpeas Brother (author)  rimar20006 months ago

That's interesting. Here in the U.S., I got acetone from my local Walmart for 6 dollars over the counter. Why is it so hard to get in Argentina?

kymyst told me that a styrofoam-acetone soluion works as a cement for PVC. I'll have to try it sometime, because that actually sounds useful. :)

you should try biodiesel and styrofoam, it completely disappears.

Chikpeas Brother (author)  liquidhandwash6 months ago

Neat! Where can I get biodiesel? Is there a video showing the process?

I dont know if you can buy bio where you are, you may have to make it

have a look at

or google "making biodiesel"

Okay, thanks.

Gee, that looks super for the environment.

The acetone evaporates and the styrofoam mixture can be burned away. No harm done. :)

I seem to recall reading, many years ago, about a doctor who did something similar with discarded pudding cups and either acetone or tolulene (can't remember which)... he used this mixture to cast prosthetic limbs and was using this method to bring prosthetics to third-world countries.

Cool! Thank you for commenting.

Either acetone or toluene will dissolve styrofoam, but acetone is non-toxic. Gasoline will also work.

This mixture can be used as a cement for plastic items ( ABS, polystyrene and PVC ) if it is made thick enough. One small correction, acetone is not classified as a toxic chemical, but it is still a good idea to avoid inhaling the vapour.

Chikpeas Brother (author)  kymyst6 months ago

That's very interesting. Thanks for sharing!

I was under the impression that acetone fumes were considered slightly toxic. Is this incorrect?

Acetone vapours are mildly irritating to the respiratory tract and may cause headaches on prolonged exposure, but they are not toxic in the accepted industrial hygiene sense of being acutely poisonous. The occupational short term exposure limit for acetone vapour is 1000 parts per million, which is quite a high vapour concentration. Substances with toxic vapours typically have exposure limits of less than 5 ppm.

I see. Thanks for letting me know!
