LAVA LAMP | DENSITY EXPERIMENT | HUNGRY SciANNtist

MATERIALS

oil
water
food color
alka-seltzer
tall glass/ bottle
This experiment shows that oil floats on top of the water because it is less dense or lighter than water. The food coloring has the same density as the water so it sink through the oil and mixes with the water.

When you add the tablet it sinks to the bottom then starts to dissolve. As it dissolves it makes gas, carbon dioxide.

The air bubbles bring some colored water with them to the top. When the air comes out of the colored water, the water gets heavy again and sinks.

Enjoy doing this experiment at home!
