Website Detail Page

published by the Exploratorium
This Exploratorium site contains an activity about afterimages. You'll stare at a shape on the screen for a while and then when you look away, you'll see the same shape in a different color.  The site provides an explanation of what happens and supplies some extension activities, including one using a green, black, and yellow American flag. This activity is part of Exploratorium's Science Snacks series.
