How can I make a good homemade lava lamp?
assistant
To make a good homemade lava lamp, you will need some oil and water. Start by filling the bottom of a glass container with oil. Then, fill a second glass container with water so that it is about one-third full. Next, put a small amount of food coloring in the oil. Finally, add some drops of dishwashing liquid to the oil and swirl them around with a toothpick or spoon.
