Crack and shake one glow stick until it is completely lit up. Wait 30 seconds until the water has mostly settled to the bottom.
Reply Upvote. Salt is heavier, or more dense, than water, and sinks to the bottom. Using stuff you probably have lying around the kitchen, you and your family can make your very own lava lamp and learn a bit of science while doing it!
Oil is lighter, or less dense, than water, so it rises to the surface. I thought glow sticks only lasted 12-24 hours. They were not hard to make and the results are stunning! The glow of the lava comes from either phosphorescence or fluorescence, depending on the chemical you used.
Does the size of the bottle affect how many blobs are produced? As the gas bubbles rose, they took some of the colored water with them. A liquid show for the eyes. Use common household ingredients to make a safe lava lamp that glows in the dark.
Fluorescence occurs when a material absorbs energy and almost immediately releases light. Other times my kids come up with brilliant ideas that result in some pretty amazing things. Did you make this project?
Check out the book. When the blob of water reached the top, the gas escaped and down went the water. Name E-Mail Address.
