Acetone vs Styrofoam - The Results Are Wild
Dissolving Styrofoam With Acetone Experiment
Acetone vs Styrofoam - The Results Are Wild
Made for parents and teachers
Hey, welcome back to Kids Fun Science! Today's experiment is the vanishing styrofoam. This *chemistry* demonstration shows the fascinating process of *dissolving styrofoam* using *styrofoam acetone**. It's one of those amazing **experiments to do at home* that makes *science for kids* truly engaging, explaining why styrofoam seems to disappear right before your eyes.

Styrofoam is an extruded polystyrene foam that is trademarked by the Dow Chemical Company. It is actually polystyrene that has had air pumped through it to increase the amount of air bubbles in the polystyrene.
Styrofoam Acetone Experiment
To carry out an experiment with Styrofoam and acetone, all you need is a large bowl, gloves and safety goggles. Use Adult Supervision. Pour the acetone into the container, then slowly add pieces of Styrofoam. You can use a large piece of Styrofoam, Styrofoam beads or even a Styrofoam cup. I did this by pouring the acetone directly onto the Styrofoam head.
Do the experiment in a well-ventilated room, and wear safety glasses and gloves. Styrofoam dissolves in acetone in a similar way to how sugar dissolves in water. It is a physical rather than a chemical reaction. The air in the foam leaves, and because Styrofoam consists mainly of air, when it dissolves in acetone it completely loses its structure. The acetone splits up the long chain of molecules, and the air disappears, causing the volume to shrink radically.
The Styrofoam does not completely disappear, even though it looks like it has. Rather, the polystyrene molecules are actually present in the acetone solution. The reaction between Styrofoam and acetone shows how soluble this plastic is in an organic solvent and how much air is in Styrofoam.
It takes about 24 hours to have the Styrofoam harden.
