How to Make Lava Lamp - Science Experiment for Kids

You can try this experiment with your kid, because it's so easy, interesting and beautiful.

For this experiment you are going to need one glass (or bottle, vase), vegetable oil, water, food coloring and Alka Seltzer (or effervescent vitamins).

First you pour water in the glass and then pour vegetable oil. Try to pour oil on the side of the glass, so you don't make too many bubbles.

Anyway, if you make a lot of bubbles, let it rest for a while.

When water and oil separate and majority of bubbles are gone, add few drops of food dye. Food coloring won't dissolve in oil, but instead it will submerge until it reaches water. In some cases it will dissolve in water right away and in other cases it will stay between oil and water as bubbles. This is because there is thin film of oil outside the bubble which prevents it from mixing with water.

After that, you just drop one Alka Seltzer into the whole thing, relax and enjoy the view. I used effervescent vitamin C. I think this way reaction is more bubbly then with Alka Seltzer.

When lava lamp uses all the "power" of tablet, just add another one. I added five or six in a row and it was working like a charm.
