Floating and Sinking Elves: It uses the principle of Pascal, gravity and buoyancy.

When gravity exceeds buoyancy, the little elf sinks.

When gravity equals buoyancy, the little elves hover or float.

When gravity is less than buoyancy, the little fairy floats upward.

Placing two small elves is good for students to compare the amount of water in the elves when they are smaller. When the elves sink, the pressure applied to the bottle is different!
