Last time I went on a household cleaning spree, I decided to clean out our family medicine cabinets. I found a lot of items left behind from previous house guests, items that my family doesn't use - but I didn't want to toss them in the trash. I started considering creative ways that I could use them. When I came across a package of Alka-Seltzer, I figured that since it fizzes and bubbles when added to water, I could use them to make lava lamps with the boys. We headed outside with the Alka-Seltzer tablets and a few other items from our kitchen cabinet and recycling bin. What ensued was an afternoon packed with learning fun as my boys created lava lamps using these ingredients. Read on to learn how you can and your kids can create this science experiment too.
What You Will Need for Recycled Lava Lamps:
- empty bottle
- cooking oil
- water
- food coloring
- Alka-Seltzer
Step 1: Add the Oil
Have your child fill an empty container 3/4 full of cooking oil.
Step 2: Add the Water
Then, fill the rest of the bottle with water, leaving about an inch of bottle empty.
Step 3: Add a Little Color
Let your child drop 10 droplets of food coloring into the bottle.

how long with the alka-seltzer last?
It only lasts a couple of minutes – that is why you break it into small pieces, so you can add more.
