Stalagmites and Stalactites
Materials:
- 2 jars with warm water
- Baking soda
- String 12” long
- 2 weights

Fill two jars with warm water. Add baking soda to each and stir until no more dissolves. Tie weights to the ends of a 12 inch piece of wet string. Place one end of the string with the weight into each jar. Position the jars approximately 6 inches apart and place a small plate underneath the string. Check the jars every day and watch the stalagmites and stalactites grow.
