How to Build a big ass lava lamp

To create a massive lava lamp, you're going to need vegetable oil, Alka Seltzer, food coloring, and a water jug (a massive jug, like the ones you see in offices). Fill about one fourth up with water, and use vegetable oil to fill the rest. After filled, use an entire bottle of food coloring. After the food coloring floats to the bottom of the oil, take the jug to a safe area with some kind of light shining through the jug. Finally one by one drop the Alka Seltzer (about 34-36) into the water, creating a lava lamp effect.
