Roni and Daniel demonstrate how chocolate mousse can be made from two simple ingredients: chocolate and juice. Because chocolate already contains lecithin, an emulsifier, no eggs are needed in this recipe. Children get a lesson on solubility as well as an afternoon snack!
(Left and middle) Karen and Connor talk with the children about water-loving and water-hating properties of different materials like water, shaving cream and food coloring. (Right) The children use spectroscopes to see the different colors in white light.
