Building a Ping-Pong Ball Launcher: Tips and Ideas from Experienced Makers

AI Thread Summary
To build an effective ping-pong ball launcher that shoots 12 feet into three coffee cans, it's crucial to determine the correct elevation angle and tube length. Users suggest that a 30-degree angle may provide optimal trajectory for the launch. The proposed tube length of 1 foot 6 inches, combined with a 6-inch elevation off the table, is likely to achieve the desired distance if calculated correctly. Experimentation with different angles and adjustments may be necessary to refine accuracy. Collaboration among makers can enhance the design process and improve results.
