how to make a water rocket launcher
Water rockets have been around a long time, but really got popular when soda manufacturers started packaging soda in 2-liter bottles back in the mid-’70s. Since they were considerate enough to give away free rocket bodies with every soft drink purchase, many of us started building rocket launchers to fly these new rockets.

Water rocket launchers are fun and easy to build if you have a few household tools, but there are some tricks that are not obvious at first. You’re going to hold a rocket on a pad while it is under as much as 75 psi of pressure. That’s not easy to do. This one uses high pressure O-rings and a zip-tie mechanism to securely hold the rocket in place until launch time.
