For this we need:
Two liquids of different densities, take sunflower oil as the main liquid, and ordinary tinted water is suitable for the other. We will also need any capacity - be it a bottle or a glass jar. And another ingredient is effervescent tablets, for example, alkozeltser or anti-influenza. After you have collected all the ingredients - proceed to the manufacture. In the prepared container - pour a little tinted water, and gently pour the oil on top 3-4 times the volume of the dye.
Liquids will not mix together - this is due to the fact that the density of water is greater than the density of oil, so it will always settle to the bottom. To begin the process, we will throw an effervescent tablet into a container in liquids - gas will begin to release and water, together with air bubbles, will rush up, and then it will slowly sink to the bottom in the form of beautiful balls.
I also used soy sauce as dyes
and paint from bright, acid-colored markers.
This process looks much more spectacular on the video:
