These clear-view pumps are a great way for young learners to observe cause and effect as they experiment with water! Children simply submerge the base…pump the chunky knob up and down to fill the chamber and build pressure…then watch the water flow! Set includes 4 durable plastic pumps; each measures 13".

Water Fun
September 06, 2025 - By Vanessafrom Chino Hills, CA
I've been looking for a manual water pump for kids for a while. I like the functional sinks in mud kitchens and montessori sinks but I never made the investment since my kids can easily access our backyard faucet. However, I was so excited to discover this pump as a fun addition to water play. My 4 and 7 year old kids were immediately intrigued. It works great. It takes a few pumps to fill the tube and then the water splatters out. I love that the tube is clear so that you can see the process happen.
Yes, I would recommend this product.
