With the Teaching with Toys: Drinking Bird and Hand Boiler—ChemTopic™ Lab Activity, play with two toys that demonstrate scientific concepts. The “drinking bird” lets students discover evaporation and the effect of temperature on vapor pressure while a hand boiler, a closed glass apparatus with two bulbs connected by spiral glass tubing and some colored liquid, lets students boil the liquid inside with just a touch of the hand.
