PART SIX: Polystyrene - A Thermoplastic Polymer

The acetone is located in the squirt bottles, transfer a small amount into a petri dish. DO NOT SQUIRT ANYONE WITH THIS CHEMICAL! If you spill any acetone on your skin, your skin will feel cool as it evaporates. Acetone has a low boiling point and the temperatrue of your body is well above the boiling point of acetone. Since converting a liquid to a gas requires heat, the heat is supplied by our body, we feel cool when it evaporates. Do not inhale the acetone vapor as it could cause headaches. Keep the acetone away from plastic, or any rayon garments. Why? Lets see what acetone does to styrofoam.

Place a styrofoam cup into the acetone in the petri dish.
