Thames and Kosmos Water Power: Rocket-Propelled Cars, Boats, and More

• Build splashy STEM projects that run on pressurized air and water—no batteries needed

• Assemble six working models: water-rocket cars, jet-propelled boats, a water gun, and more

• Discover action–reaction forces, rocket propulsion, pneumatics, and why air + water = max thrust

• Hands-on tests let kids tweak blade angles, water fill levels, and air pressure to optimize performance

• Safe, backyard-friendly experiments that connect real-world engineering to rockets, organs, and sprinklers

• Durable parts and a guided manual support repeatable builds and open-ended tinkering
