After looking at something bright--such as a lamp or a camera's flash--you may continue to see an image of that object when you look away. This lingering visual impression is called an afterimage. Follow instructions closely! The experiments in The Exploratorium Snacks 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.
