Thermodynamics for Science Classrooms

Hand Boilers, perfect for teaching about thermal energy, are sold individually and in cases of 12 for your entire class. Click a metal disk in the Chemical Heat Pack and watch the liquid crystallize. When two 1-pound, 2-inch diameter, Smashing! Steel Spheres are smashed together, enough heat is generated at the point of contact to burn a hole in a piece of ordinary paper! Place an ice cube on each of the Amazing Ice Melting Blocks at room temperature. One ice cube instantly begins to melt and is totally gone in about 90 seconds while the other ice cube shows no evidence of melting. Amazing!
