A Homeschooling Project – a Groovy Lava Lamp!

We combined some ingredients we found around the house to make a very mesmerizing and reusable lava lamp.  All you need is an empty water bottle with the label removed, vegetable oil, water, food coloring (one color), and an Alka-Seltzer tablet.

Just fill the bottle a little over halfway with the oil, then add water, stopping about an inch from the top.  Add around ten drops of food coloring.  Cut or break the antacid tablet into quarters and drop one quarter into the bottle.  The lava lamp will then come to life!  When the bubbling slows, add another quarter-tablet to get it started again.  You can keep doing this as long as you’d like!

You can also store this project by letting it sit until all the bubbles have completely dispersed.  Then you simply cap it and store it in a safe place until the next time you would like to use it.  My boys had so much fun with this project that they did not want to stop.
