COLUMBUS, Ohio (WCMH) — Storm Team 4’s meteorologist Liz McGiffin caught up with Kelli Kinzig Manager, of Education Experiences at COSI, to talk about the new exhibits at COSI and do a fun Halloween science experiment.

The experiment demonstrates the chemical reaction that happens when acetone and Styrofoam are combined, using some Halloween-themed props. The chemical dissolves the bonds that hold together the Styrofoam to release air and it ends with an imperceptible result.

You can watch the demonstration in the video player above.

If you try this experiment, there are a few safety notes that you should keep in mind. Acetone is a highly flammable chemical and should be handled with care. This experiments should be performed in a well-ventilated area, preferably under an exhaust hood, or in an open air/outdoor environment if possible. You should wear protective eye wear at all times. Dissolving polystyrene releases a gas in the form of bubbles that may cause the acetone to splash. If you splash any acetone on your skin or in your eyes, rinse thoroughly with water immediately.
