The heat from your hand holding the bottom chamber warms the liquid so it starts to vaporize and then expand. The pressure pushes it to the top chamber through the tube that goes from the bottom. When all the liquid has gone to the top, a bubbling effect is created.
When you let go, the liquid cools and starts to return to the bottom. By placing you hand briefly around the top chamber it will warm the top and push all the liquid back to the bottom chamber.
