In response to KK,
Acetone is no more than finger nail polish remover so the hazard to you heath is no more that removing finger nail polish.

In response to patrick,
If the acetone evaporates away then the remaining glop is styrofoam but without the air bubbles. No more toxic than the original packing peanuts. There is no chemical reaction going on, the styrofoam is dissolved in the acetone. If this is hard to comprehend, think of dissolving sugar in water and then letting the water evaporate. At then end you'll be left with a big glob of sugar.
