Description

This list provides a one-stop forum on homemade rockets powered by compressed air and water, and related topics.

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!

The list has a history dating back to 1997, but moved from a private service to Yahoo in 2003 with 170 members and 17,000 messages in the archives. The old home page may be still available at http://cjh.polyplex.org/rockets/list/

Postings by new members are moderated (must be approved), until the new member is promoted to full posting status. This helps keep the group free of spam - spammers are quickly banned. Sorry for any inconvenience this might cause.
