Stalactite experiment
Science experiments are so much fun for kids and so easy to do in your own home. This experiment will keep the kids intrigued over the 2-3 weeks as they watch the change taking place.
What you need:
- two glass jars
- baking soda
- spoon
- string
- paperclips
- water
- saucer
Number of players:
1+
Activity:
Fill the two jars with hot water.
Add as much baking soda as will dissolve to each jar.
Mix well.
Cut a piece of string and tie a paper clip as a weight to each end.
Dip each end into each jar.
Place a saucer between the jar to catch the drops.
Leave the jars for 2-3 weeks and a stalactite will grow!
Why?
The baking soda mix is carried through the string and drips into the saucer.
Over time the dripping water evaporates forming a tiny stalactite and stalagmite.
