Water rockets are typically made from discarded plastic soft drink bottles, partially filled with water, pumped with air to high pressure, and released. Single stage rockets can reach 500 feet, with top speeds over 100 miles per hour!

Advanced rockets may use other materials, other gases, or no water. There are no rules, except to learn while having fun!
