<human>: Can you tell me how to make a DIY lava lamp?
<bot>: To make a DIY lava lamp, you will need some glass or plastic bottles, oil or water, food coloring, and an empty jar. Start by pouring the oil or water into one of the bottles. Next, add two drops of food coloring to each bottle and shake it up. Place the second bottle upside down inside the first and secure with a rubber band. Fill the empty jar with water and place it in the center of the two inverted bottles. Lastly, light a candle near the jar so that the flame flickers and creates a hypnotic effect.
