In order to create the lava lamp effect, you will need the colored Magic Flow Lava drip solution and Mineral Oil.  Magic Flow™ LAVA drip takes creating lava effect tumblers to a new level! This listing is for 8oz bottles of Lava drip solution. Shake well prior to using.  These work best in tall tumblers. We recommend the 24oz Acrylic Tumblers. Start with any glitter you want to add to your tumbler. Chunkier glitter will flow through the Lava and the Mineral Oil while finer glitter will stay mostly confined to your mineral oil. 2. Squeeze or pour 2oz of mineral oil into the 24oz tumbler. If you want to color your mineral oil, use oil based food coloring.3. Coat the inside wall by turning the cup sideway and spinning 3-4 times until well coated. 4. Shake well and pour in about 4oz of Lava drip. 5. Plug the hole and enjoy! Using another brand of mineral oil could affect your flow.
