How to Make a Lava Lamp
Have your kids ever wanted a lava lamp? Well now they can make their own using every day household items! This is a fun and inexpensive way to make your very own lava lamp!
- Empty and clean 16 oz. plastic soda bottle with the lid
- Vegetable oil
- Food coloring
- A large Alka-Seltzer tablet
What you do:
Fill the bottle 3/4 full with vegetable oil. Add water to the remainder of the bottle, almost to the top but without it overflowing. Add 10 drops of food coloring, to make the solution appear fairly dark.
Cut the Alka-Seltzer into 8 pieces. Drop one of the tiny pieces into the oil and water mixture. The mixture will start to bubble.
Wait until the bubbling stops and add another piece of Alka-Seltzer. Continue until there is no more Alka-Seltzer, and the bubbling has completely stopped.
Screw on the cap of the soda bottle. Tip the bottle back and forth and watch the waves appear.
