Just Fill the bottle 3/4 full with vegetable oil.
Fill the all of the bottle with water (almost to the top but not overflowing).
Add about 10 drops of food coloring. Be sure to make the water fairly dark in color. Notice that the food coloring only colors the water and not the oil.
seperate the Alka-Seltzer tablet into only 8 pieces.
Drop one of the tiny pieces of Alka-Seltzer into the oil and water mixture. When the bubbling stops, add another chunk of Alka-Seltzer. It’s just like a lava lamp!
then when you have used up all of the Alka-Seltzer and when the bubbling has stopped, screw on the soda bottle cap. Tip the bottle back and forth then see the wave. The tiny drops of liquid join together to make one big lava-like blob.
