Picture of Water Bottle Rockets
These instructions detail the steps involved in building a water bottle rocket. These rockets use pressurized air and water to fly hundreds of feet in the air, and make a great science project for use at home or in the classroom.

This rocket project is suitable for ages 8 and up with adult supervision, and should take less than 20 minutes to build. 

WARNINGS
• Never launch your rocket in a busy area, an empty field is a good place. 
• Never attempt to retrieve a rocket which has landed in power lines or in another dangerous situation. 
• Never launch your rocket in any direction but straight up. 
• Never over pressurize your rocket, follow the pressurization instructions of your launcher. 
• The writers of these instructions assume no liability for your safety, please use common sense and caution when launching a rocket.
