To celebrate Star Wars Day can you create your own lava lamp?
What You Need:
- Flask or bottle
- Vegetable oil
- Water
- Food coloring
- Alka-seltzer
What You Do:
- Fill the flask most of the way with vegetable oil.
- Fill the rest of the flask with water. The water will sink to the bottom under the oil.
- Add a few drops of food coloring; your choice of color. The food coloring is water-based, so it will also sink and color the water that is now at the bottom of the flask.
- Break an alka-seltzer tablet into a few small pieces, and drop them in the flask one at a time.
- Watch your lava lamp erupt into activity! As the reaction slows down, simply add more alka-seltzer.
Make sure to send some pictures of your experiment to the Long Mynd class email!
