Do the Eco-Foam Fizzle! Make a slimy ooze! Make a strange and goofy substance that flows, stretches, breaks, and bounces. Learn about the chemistry behind polymers, cross-linking, gels, phosphorescence, and the quantum leap.The REGULAR KITS (singles) include enough materials for repeating each experiment 2 TO 3 times. The larger CLASSROOM KITS contain 5 times the materials of the single kits, enough for a 5 STATION CLASSROOM SETUP that can be REPEATED APPROXIMATELY 3 TIMES.
