Water Pump

💧 Build Your Own Mini Water Pump!

Discover the magic of engineering with this clever Water Pump Kit, made from simple, everyday materials — a takeaway cup, syringe, plastic tubing, and tiny ball bearings. Children learn how real pumps move water while experimenting, building, and having fun!

This kit introduces key STEM principles such as pressure, flow, and one-way valves — all through a playful, creative project that fits perfectly with the Australian Curriculum’s Design and Technologies strand.

The secret is in the mini ball bearings, which act as valves to control the flow of water. Watch as students pump water from the cup and fill a balloon or create their own ideas.

Kit includes:

4 oz takeaway cup (reservoir)

5 mL syringe (pump body)

Rigid plastic tube and flexible outlet hose

Ball bearings for one-way valve control

Easy-to-follow illustrated instructions

Once students have built their first pump, they can experiment with new ideas — connect multiple pumps, test how high the water can go, or power a model garden or water feature!
