Welcome to the Water Rocket Forum, sponsored by The Water Rocket Achievement World Record Association.

The largest, most sophisticated and ground breaking group supporting you, the serious water rocket flyer! Whether you are a beginner or an expert, the WRA2 has something for everyone.

A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is constructed from thin plastic or other non metallic materials (usually a used plastic soft drink bottle) weighing 1,500 grams or less. The water is forced out by compressed air. It is an example of Newton's third law of motion.

Wing Attachement Help

Post by LearningRockets » Sat Oct 01, 2011 4:21 pm

Hello, I am a middle school science teacher. The students want to build some rockets. I have tried building your standard 2 liter Coke bottle rocket. I have tried hot glue and tape to keep the wings on but they fall off after 2 launches. Any suggestions as to how I can better attach them to the bottle ? I am using 3/16" foam poster board from Staples office supply for the wings.
Thank you for ANY help/suggestions.

What type of glue are you using? A lot of glues will not stick to plastic, so the fins will peel right off. One glue that works exceptionally well is called "PL Premium Construction Adhesive". Many Water Rockets are made from multiple bottles cut and glued together with this glue and it holds hundreds of PSI pressure without coming apart, so it will hold your fins on with no trouble. In fact, you probably couldn't get them off if you wanted to!

Good luck!

When working with PL premium, make sure you use some latex gloves. The stuff is difficult to get off your skin. Also make sure you work in a well ventilated area, as PL gives off potentially harmful fumes even though you can't smell them. When you're done gluing, seal the end of the tube really well to stop atmospheric moisture getting into the tube, otherwise it will set in the nozzle.
