You will need
  • - acetone
  • - glass container with lid
  • - Styrofoam
Remove the lid from the glass container and pour in a small amount of acetone (approximately 1.25 cm from the bottom). If need be, add more later.
Break the Styrofoam into small pieces and throw them in a container of acetone. Material in contact with the liquid will begin to dissolve. If you need to get more plastic – just add a little acetone, and then crumble more styrofome.
Wait about 5 minutes to allow the excess acetone to evaporate. If you want to give the plastic some form, wait an extra minute – by this time, the plastic will be easy to succumb to the moulding. Plastic ready, you can sculpt.
