Whipping up a batch of gelatin demonstrates how to dissolve a powder into liquid, then how to cool a liquid into a jiggling but solid mold. Pour the contents of a package of instant gelatin into a bowl. Let your child touch and taste the grainy powder. With your child well back from the bowl, stir in 1 cup of boiling water for about 2 minutes, until the powder is completely dissolved. Explain that the hot water is dissolving the little grains of powder into the liquid.
Next, mix in 1 cup of cold water, then put the gelatin in the refrigerator until it has firmed up. Tell your toddler that adding water and cooling the liquid will help it to become a solid. Scoop out a piece of the solid gelatin and let your child touch and taste it.
