Introduction: How to Make a Cup Chemically Disapear

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.

No, it's just a thick, very sticky, slowburning and flammable liquid. Not an explosive and certainly not HE =).

Gasoline + Styrofoam = Napalm? Not being a smarta**, just curious

author
sameotoko made it! (author)sameotoko2008-12-04

Gasoline + dishwasher fluid = Molotov
Gasoline + Candle wax = Hell paste
Potentially fatal, be extra careful.
Not to be tried with kids around

sameotoko made it! (author)sameotoko2011-07-08

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

author
FuyuKitsune made it! (author)FuyuKitsune2010-05-04

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.

Styrofoam and acetone are different, right? They have different polarities. So they react each other.

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!
