Liquid Chalk

 After we played with our solid chalk this week we were wondering if we could make a liquid chalk.  By combining water, corn starch, and food coloring we made Liquid Chalk.  We discovered it was very difficult to write with our liquid chalk.  We used sponges, sticks, leaves, and anything else we could find to write with our liquid chalk.  Some friends discoved that by adding more water the liquid chalk was easier to draw with.  Check out our discoveries here, Liquid Chalk.
