Step 4Plug on end of rocket tube...
This is a very, very important step and time and attention to detail are essential.
1. Use the PVC pipe to trace 5 to 6 circular plugs. You can make one trace and fold up the card stock and cut them out at the same time.
2. Slip the dried rocket tube back on to the PVC pipe and slide it down until the PVC tube is 1/4 inch from the edge of the rocket tube. This will give you a foundation for gluing the plugs.
3. Place one plug on the foundation and spread a bead of white glue around the edge. Use your finger to spread it evenly over the whole plug and let it sit for a few minutes. Then take another plug and place it on top of the first and repeat the process. Continue this way until all the plugs have been used.
4. Set the PVC pipe-rocket tube vertically and let it dry for at least 24 hours.
Keep in mind that all the air pressure of the launch tube must be contained in the rocket cylinder. If the plugs are weak, the nose cone will be blown off the rocket and the rocket will remain on the launch tube. There is no such thing as too much reinforcement and make sure to let the plugs dry at least 24 hours.
