Lava Experiment

Our project is making a lava lamp in a bottle. My group members are Erik Duarte, Isaac Sanchez, Kenneth Loya, and Nick Mahan. Our question was can you make a lava lamp out of household items. Our hypothesis was you can if you find the right items. We were right you can if you put vegetable oil on top of water and then put the food coloring in and the ad Alka-Seltzer. Our background info 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 I to 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. The conclusion is that you can make lava lamp household items if you use Alka-Seltzer, water, food coloring, and vegetable oil. So if you want to try just do what we did. That is our experiment. Why this happened because the Alka-seltzer had a chemical reaction beacuse of some powder on the outside of the alka-seltzer so the bubbles carried the food coloring up to the top of the bottle
