Materials:

Small water pump

Transparent water pipe

Some stones or beads

injector

Steps:

Put the water pump in a basin or sink, turn on the power and test whether it can work normally.

Connect the transparent water pipe to the water outlet of the water pump, and put the other end on the nozzle.

Put some stones or beads in the container under the shower head so that the sprayed water can wet them.

Turn on the water pump and water will be pumped to the nozzle.

When the water flows to the nozzle, it will wash out the stones or beads at the bottom and form a splash.

After the small experiment is completed, the effect of the fountain can be adjusted by changing the shape of the nozzle or adjusting the speed of the pump. In addition, food pigments or fluorescent agents can be added to make the water more tasty. Attention, be sure to use safe power supply and equipment to avoid putting your hand into the water when the pump is running.
