4M Water Rocket Kit
Great fun my son loves it. When the kids saw it on the soccer field the playground emptied out and all the kids came to watch and launch the rocket.
The 4M Water Rocket Kit is really cool - teens will love to build their own water rocket with a recycled soda bottle. The power of the water pressure on this rocket blasts it up to 90 feet in the air - teens who enjoy science projects and experiments will want to do this over and over.
