We're going to watch how density works by making a simple lava lamp that doesn't need electricity! If you like to watch blob-type shapes shift and ooze around, then this is something you're going to want to experiment with. but don't feel that you have to use the materials mentioned below - feel free to experiment with other liquids you have around the house, and be sure to let me know what you've found in the comment section below.
All you need is about 10 minutes and a few quick items you already have around the house. Are you ready?

Changing temperature of the oil affects the rate the the salt falls through it. Changing the temperature of the water affects how the salt dissolves into the water.
If the effervescent tablets are small, they are too light and will remain suspended in the oil.
Hi there we tried the cold water and warm oil combinations. What are the differences we are supposed to notice? And if there is a difference to notice, what is the reason for it? Also tried the tablets – what is the reason why the small chunks get stuck in the oil and don’t go down to the water? Thanks in advance for you answers.
No, you’ll need to keep adding more salt!
Does the lava lamp work for a long period of time without a constant supply of new salt?
This experiment is so cool! I’m constantly asking for a lava lamp XD
