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.
