The document provides instructions for making a lava lamp using an empty bottle, vegetable oil, water, food coloring, and Alka-Seltzer tablets. It explains that the oil and water will not mix, with the oil sitting on top, and that adding Alka-Seltzer tablets to the water will produce carbon dioxide bubbles that pick up the colored water and carry it up and down the bottle, creating the lava lamp effect.

LAVA LAMP By Ethan Alcock
MATERIALS Empty bottle Vegetable oil Water Food colouring Alka seltzer tablet
WHAT TO DO Get the empty bottle Fill it with vegetable oil about three quarters full Fill the rest of the bottle with water Add about ten drops of food colouring Break the tablet into four pieces Add the tablets to the bottle one by one and watch what happens When you have added all the tablets, put the lid on the bottle and tilt it from one side to the other.
WHY Oil and water do not mix, the oil sits on top of the water. When you add the Alka Selzer to the water it starts to make carbon dioxide, which makes bubbles. Because we have added food colouring, the gas attaches itself to the colour and makes it move. When the bubbles reach the top of the bottle they pop and fall back down making the colour go all around the bottle.
Thanks for watching!
