Human: Can you tell me how to make a DIY lava lamp? Assistant: 
To make a DIY lava lamp, you will need some glass containers with lids and oil. Start by filling each container about halfway with the oil. Place the filled container in a cool dark place for 24 hours. After 24 hours, add food coloring to one of the containers. Make sure the color is evenly distributed throughout the liquid. Then, remove the colored oil from the container and replace it with plain oil. Replace the lid and place the container back in the cool dark place. Repeat this process every day for 3-5 days until the color starts to separate into layers. You can then enjoy your homemade lava lamp!
