Styrofoam is a polymer and when brought into contact with
acetone the polymer breaks down into its monomers. This
demonstration show the process of depolymerization. It looks pretty cool.

Need a Petri dish (something that is not Plastic to hold Demonstrations in
Styrofoam Cup is placed into petri dish and 20 mL of acetone is poured in

Clean up let acetone evaporate, throw out cup gew.

acetone can be replaced with a number of different solvents like gasoline.
I'm not that great with chemicals and stuff like that, but what's napalm?
a high explosive
put it in a pipe and make a wireless sparker... you will get a nice little boom
No, it's just a thick, very sticky, slowburning and flammable liquid. Not an explosive and certainly not HE =).<br/>
noo, dont use gas unless you want napalm
Makes &quot;cheap&quot; napalm not real napalm...
you could also do that with mountain dew, or gas but the resulting substance is napalm like
haha you cant do that with mountain dew.
my 8th grade science teacher had a party before christmas break and sombody left a styrofome cup half full of mountain dew on the table that never got thrown away and when we got back he said it desolved the bottom
and it kills sperm
Not all Mountain dews do that only the red kind.
<a rel="nofollow" href="http://www.snopes.com/medical/potables/mountaindew.asp">course it does</a><br/>
good so its fake<br/><br/>yay!<br/><br/><em>goes of and drinks gallons of mountain dew</em><br/>
not chemically possible...he's just yanking your chain for not cleaning up after your self.<br />
it's like the wonder drink.
its gooooooood
can you get the chemicals in nz or what out of?
VERY VERY VERY COOL!!! but all i know about styro is if u cut it, its bad for the ozone... those any body know if this is eco friendly??? (not much of a chemist) <br>
its bad cause it releases a type of gas thats pretty bad,(i forgot what kind of gas it was but you can do this outside) and when the cup is melted, its like napalm, you can light it up and acetone can be found it nail polish remover
now... wen u said napalm... ur saying napalm BOOM BOOM.. like in the movies? <br>
but not water...
Oh boy, replace acetone with gasoline and you get napalm!
Gasoline + Styrofoam = Napalm? Not being a smarta**, just curious<br/>
Gasoline + dishwasher fluid = Molotov<br/>Gasoline + Candle wax = Hell paste<br/>Potentially fatal, be extra careful.<br/>Not to be tried with kids around<br/>
wats hell paste???
it's a super-saturated solution of styrofoam in gasoline. It forms a sort of waxy liquid that can be used for incendiary purposes. Do not try it
what whould the dishwasher fuild d? any chemical formuals? and candle wax does what?
dishwasher soap like dawn, thats the main ingredient no one knows about, with out the fire will not stick to anything, and it will go out almost instantly
Its more commonly called Poor mans Napalm cuz it isn't technically Napalm
actually it is napalm (or at least the old type of napalm). Napalm is (or was, they may have changed it) part polystyrene, part gasoline, and then a little accelerant to make sure the flame ignites every bit of napalm before it splatters.<br />
Yup, google it, it's all over the place.
which one
I tried it, it works.
Napalm the f****rs just like in nam
you can use a finger nail polish remover with acetone in it, it will also dissolve cigarette butts of course the unused butts have a white look the used ones are yellowish to orangeish anyway have fun
thanks to the ciggie butts being made up of cellulose acetate fibres. which you already knew, but im just putting in that little bit of trivia for those that don't.
Im melting - wizard of oz
Styrofoam and acetone are different, right? They have different polarities. So they react each other.<br />
Someone came into our school and said in the wizard of oz, the witch disappered by dorothy throwing water on her. Then he took out a witch head made of styrofoam and threw acetone on it but he said it's water (then he explained it wasn't). The witch head melted lolz!
were do u get acetone?
its called nail polish remover
where does he get all of these crazy chemicals?
acatone is sometimes called nail polish remover and the foam cup you can get anywhere
cool dogg
I think you mean "goo" not "gew."
Then you can take the melted plastic, dry it, shape it, and dry it again and form pretty things!
dude, actone can make lots of things disappear...
acetone can be bought anywhere
