When two different-colored lights shine on the same spot on a white screen, the light reflecting from that spot to your eyes is called an additive mixture because it contains the colors from both lights. We can learn about human color perception by using colored lights to make additive color mixtures. Your hand is not always a good thermometer. When you touch a variety of materials, some will seem warmer or colder than others, even when they are at the same temperature. Follow instructions closely! The experiments in The ExploratoriumSnacks Online were designed with safety and success in mind. But even the simplest activity or the most common materials can be harmful when mishandled or misused. Use common sense whenever you're exploring or experimenting.
