How Do You Make Homemade Lava Lamps?
Lava lamps, iconic trademarks of the 1960s, are entrancing decorations that can be created at home from normal household ingredients. Whether made as a science project or as a groovy throwback to a bygone era, these creations add vivid color and movement to any room for a fraction of the cost of a store-bought lava lamp. However, homemade creations lack the continual movement, heat and lighting processes used by store-bought lava lamps. Fill three-quarters of a clean plastic bottle with vegetable oil. Fill the remainder with water. Add food coloring until the liquid is the color you want. Break an Alka-Seltzer tablet into small pieces. Add the pieces to the bottle one at a time. The seltzer causes bubbles that will carry the colored water to the top before popping and allowing the colors to slowly drift downward. Place the bottle over a light source to illuminate the effect.
