## Overview

The Water Power STEM Experiment Kit by Thames & Kosmos offers kids 8+ an immersive way to learn physics through building 6 different rocket-propelled cars, boats, and more. Combining air and water propulsion, this hands-on kit includes a full-color manual to guide users through experiments on pneumatics and action-reaction forces, making complex science concepts accessible and exciting.

## Description

Harness the power of air and water to make things move! Build water-rocket cars, jet-propelled boats, a water gun, and even a lawn sprinkler. Learn about the laws of physics and their applications in real-world engineering. When you pump air into your rocket, you increase the air pressure inside. Then when you release the clamp, watch out — the air and water mixture inside will shoot out, causing your rocket to zoom off in the opposite direction! Many machines, from the oldest pipe organs to modern day rocket ships use the same technologies that power your water rockets. Experiment to test some of the differences between water and air, and learn why your rocket needs both to go fast.

Review: Unfortunately a critical component arrived cracked and made the product useless as it could not maintain pressure.
Review: Highly recommend! Quick shipping . Very easy to order, great quality!

This water power STEM toy kit from Thames & Kosmo was a hit with my 7 y.o son and he had lots of fun building and trying out the various water powered toys and had a lot of re-playablity. BUILD QUALITY - Probably one of the best things about this toy is its excellent build quality and the fit and finish of its interlocking parts. - We have brought other similar build it yourself STEM kits for our son in the past and almost all of them are generally plagued either poor quality parts or ill fitting components that not only are difficult for kids, but also compromise the structural rigidity of the toy - We had no such issues with this STEM kit , every component was made with high quality , thick plastic that fit together very well USING/PLAYING WITH IT - Our son was able to follow the simple instructions by himself and able build out the various toys. His personal favorite was the rocket car - The pump mechanism feels solid and is airtight - The performance of the toy depends on how much air you are able to compress/pump in the tube . Our son was had a bit of difficulty compressing the air too much as it required a lot of force and asked us for help because he wanted his car to go 'fast' DISLIKES None really FINAL THOUGHTS Overall is a a very high quality STEP build it yourself kit for kids that they will sure to love and would make a great gift for them. Highly recommended
