Answer The Question With A Question Game

I'm not familiar with that kind of plastic. Can you tell me more?

[DNU] PVA (polyvinyl alcohol) is an example of a water soluble plastic. Essentially how it achieves this is that they replace the polymer's acetate molecules with alcohol molecules that help to attract water molecules, which in turn, causes the plastic to dissolve in water. However, the rate of solubility is determined by the amount of acetate molecules that are replaced with alcohol molecules. PVA is also insoluble in organic chemicals, such as gasoline, grease, fats, and other oils. "And now you know the rest of the story." :p [DNU]

Disgusting yes, but how would that cause it to melt?

Haven't you ever heard of the ring of fire? ;)
 
Discourse is exchanging information by 'talking' - what about [it had to be] datcourse?

Cheers, og
