Cupboard Crafts & Experiments: Underwater Volcano

Supplies:

• 2 clear containers, either plastic or glass, one large and one small. The small container should fit in the large container.
• Water
• One small weight or rock to place in the smaller container if it is too light
• Food coloring
• Long spoon or stick

Directions:

1. Fill large container with cold water halfway.
2. Fill the small container with hot water. (Need adult to help with hot water.)
3. Add any color food coloring to hot water and stir.
4. Place the small container, upright, into the large container of cold water.
5. Observe what happens to the hot water. Hot water will float to the top because it's lighter than the denser cold water.
6. Just like a volcano, hot lava rises up because it's lighter.
