Fill the bottle 3/4 full with vegetable oil. Put some water 2. Add water to the remainder of the bottle, almost to the top but without it overflowing. 3. Add 10 drops of food coloring, to make the solution appear fairly dark. 4. Cut the Alka-Seltzer into 8 pieces. 5. Drop one of the tiny pieces into the oil and water mixture. 6. The mixture will start to bubble. 7. Wait until the bubbling stops and add another piece of Alka-Seltzer. 8. Continue until there is no more Alka-Seltzer, and the bubbling has completely stopped. 9. Screw on the cap of the soda bottle. 10. Tip the bottle back and forth and watch the wave appear.

The reason this homemade lava lamp works is because the tiny droplets of liquid join together to make one big lava like blob. Place a flashlight with a bright beam under the bottle to illuminate the bubbles for maximum visual effect. Soda bottle with cap? Vegetable oil ? Food coloring any color ? Alka -seltzer? A cup or funnel Paper Pencil Microwave Water lamp lit from the bottom and containing a soft gel that moves and grows as the light heats it; also called lava light I chose to my topic because I wanted to know a better way to make a lava lamp without having to buy one .

With house hold materials you can do lots of neat things. Another reason I chose it because I wanted to make it look better if you have different temperatures of water.
