First of all to make the glow in the dark lava lamp you need the ingredients,like: see through-bottle,oil,highlighter water (optional), regular water and some salt.
How to make it!๐ฑ Now, get the see through-bottle and fill it up with water.Then leave about an inch with no water. (Optional) you can also dye the water with highlighter or food coloring. After you leave a little space about an inch,putt some oil at the top and add as much as u want. Lastly, wait until the bubbles from the oil disappear. In conclusion, put as much salt as u want and see what happens.
What is it happening!๐ฏ So what's happening is that the salt sinks to the bottom of the bottle. It also mixes with the oil and the water and it starts to dissolve releasing a gas called (carbon dioxide). The carbon dioxide causes little air bubbles that float to the top. This process will repeat itself over and over again until it stops bubbling so you need to add more salt.
