Ward's® Chemistry Exothermic and Endothermic Reaction Demonstrations

Tactile Demonstrations of a Chemical Reaction.

In these demonstrations, exothermic and endothermic reactions are safely carried out inside a plastic bag so students can pass the bag around and feel the results of the reaction. For the exothermic reaction the bag will become warm to the touch, while in the endothermic reaction the bag will become cold to the touch. Each kit contains all the materials necessary for five demonstrations prepackaged in the plastic bags.
