WebDec 9, 2024 · It is made of polystyrene, which is a type of plastic that is not very soluble in alcohol. However, vodka is a type of alcohol that is very strong and has a high percentage of ethanol. Therefore, when vodka is poured onto styrofoam, the ethanol will start to dissolve the polystyrene. This will cause the styrofoam to melt and become deformed.
