Water Rocket fun for $20

Water Rockets have been around for many years. My husband remembers playing with one when he was a boy. They’ve come along way since the mid 70’s, but the concept is still the same.

The kit comes with a plastic bottle that holds water. A plug holds the water in place and a bicycle pump fills it with air.

Assembly is a simple process. You simply attach the plastic legs to a small ring that screws on to the plastic bottle. There is a small plug that pops into the mouth of the bottle. The plug is attached to a plastic tube that will connect to the bicycle pump. There are different types of bicycle pumps, but there are two adapters included in the kit that will help you connect to whichever pump you own.

Once you have the rocket assembled, you pour in several inches of water and then insert the plug. Take your rocket to a large backyard area with plenty of space to shoot it off.


DO NOT stand over the rocket while someone is using the pump. If the pump goes off while you are looking over it, you could be seriously injured.

We were amazed with how good the rocket actually shoots. Now we’re just ready for another sunny (non snow covered day) so we can go shoot the 4M Water Rocket Kitagain!
