Special Effects Using Household Chemicals

In this activity on page 4 of the PDF (Behind the Scenes with Chemistry), learners make some special effects, including snow and breaking glass, with supplies found in the home. In the first activity, learners make and observe four different types of fake snow using different amounts of water and a polymer called sodium polyacrylate. In the second activity, learners make breakable glass using sugar, a hygroscopic material that absorbs water from its surroundings.

Safety notes: Adult supervision required. The sodium polyacrylate powder is irritating to the eye and nasal membranes. If you cut open diapers to remove the sodium polyacrylate, avoid shaking the diapers a lot, since doing so is more likely to irritate your nose. Always wear goggles when doing this activity. Do not put sodium polyacrylate in the sink, as it may clog the drain! Wash your hands thoroughly after this activity and follow the other safety tips on page 3 of the PDF.
