With this kit, students can witness an endothermic reaction involving reactants in the solid state. They will mix together 2 solids, ammonium thiocyanate and barium hydroxide octahydrate, in an Erlenmeyer flask with a rubber stopper. They’ll then place the cold flask in a puddle of water on a board and, after several seconds, try to lift up the flask, only to discover that it has frozen to the board. The kit includes instructions and enough materials to repeat each demonstration 7 times.
