Dry Erase

Dry Erase - March 2018 Experiment of the Month at SFFE

Materials:

  • A glass plate, bowl, or picture frame
  • Dry erase marker
  • Water

Instructions:

  1. Draw a simple picture on the glass. A stick figure is a good one to start with
  2. Pour water onto the plate or into the bowl slowly to lift up the drawing
  3. Swirl the water around to make the picture dance and move

How does it work?

The marker leaves behind mixture of pigments and a type of alcohol mixed together. The alcohol dissolves and the pigments are left behind as a solid. Glass is so smooth that the solid slides right off when it gets wet!
