Our background research is that vegetable oil is used to cook, water you used to drink and stay alive, food coloring is used to make food colorful, Alka-Seltzer it is used to make head aches go away if you put it in water and wait for dissolve. We put vegetable oil on top of water. Then we put the food coloring on top of the vegetable oil. Then we put the Alka-Seltzer in it. When it went in there it pushed the food coloring up into the vegetable witch made it go slow so it made bulbs of food coloring so it looked like a lava lamp. Why did this happen because, well the Alka-Seltzer reacted with the water naturally so the fizz pushed the food coloring up. So when it went up it ran into the vegetable oil witch is thick so it made it go into bubbles and if you have ever watched a lava lamp the lava forms into bubbles. So that’s why we call it a lava lamp inside of bottle.
