my lava lamp. I think it is pretty cool and all my guests like it so lets make one! It's really awesome it actually works like one, I think if you put a LED in there it will light up but I don't know also you can put a marble in it. Sounds like a plan.
you will need:
1.a test tube
2. some water
4. food coloring

Step 1: The Base
1. put the water, oil, and food coloring. You should get clear slow subtance in the tube, it should move slowly and creep down the tube and be like a lava lamp with colors. Since the oil floats to the top there should be bubbles that move slowly to the top.
Step 2: Add Food Coloring
add your color too make it look better. I added green because thats the only color I had and it looks good. Now you are done go display it somewhere every one can see it. Please comment, rate, and subscribe.
