    What buyers are saying
    This water rocket works GREAT! It went about 3 times higher than expected and I suggest an open field since it is not always going to land where you thing it will. The rocket in the yellow box is the original, and they do have a newer version. As for the one in the yellow box..... we went out and bought a new bicycle pump after reading the reviews that the rocket tubing would only accept the newer style Presta valve but it did not solve the problem since the valve that came with the rocket would not engage the bike pump properly. We ended up removing the attachment on the pump and straight lining the pump to the tube with a radiator clamp. In looking at the newer version of the water rocket it appears that they have addressed this problem.
