Description
Create a colorful lava lamp in a bottle using simple household items. A fun science experiment for all ages.
Ingredients
- Clear plastic or glass bottle (empty)
- Vegetable oil or baby oil
- Water
- Food coloring
- Alka-Seltzer tablets
Instructions
- Fill the bottle about 1/4 full with water.
- Add a few drops of food coloring to the water.
- Fill the rest of the bottle with vegetable oil or baby oil, leaving some space at the top.
- Once the oil and water separate, break an Alka-Seltzer tablet into pieces and drop them into the bottle one at a time.
- Watch the colorful blobs rise and fall like a lava lamp!
Notes
Store the lava lamp in a cool, dry place. The effect will need more Alka-Seltzer for a repeat performance.
