Tuck the paper underneath the pipe simultaneously as you roll. This will ensure the body is as snug as possible. If the tube slides smoothly and freely as you’re rolling, you’re in good shape.
Repeat this action of rolling a little, placing glue, rolling a little and placing glue, until the tube is sealed. Pay special focus to the last edge you glue. Ensure it is extra secure so it doesn’t unravel during flight. Continue to rub and roll the solid tube for several minutes to make sure everything is holding in place and sticking accordingly. Think of the tube as a rolling pin for dough and simply roll it back and forth.
Once you’ve smashed the edge, press the crimped end on the table to really smash it in.
This will prevent the edge from popping open once shot.
Use only a single piece of tape here so the fins have a little flexibility.
Be careful not to press too hard as you’ll puncture the taped end.
Tape the PVC and bottle together to prevent any wiggling.
Make sure the people around you know you’re about to fire.
Make sure the people around you know you’re about to fire so you don’t hit them.
If purchasing PVC from a hardware store, ask them to cut pieces to the required lengths to save time at home.
Connect the final 12” pipe by placing it into the tee.
You will have two openings pointing in opposite directions.
The final launcher will be a “T” shape with a single vertical rod sticking up front its center.
You can add blocks underneath the pipes. Doing this will send the rocket soaring across the sky in an arch, rather than straight up into the air. Play with the design by adding two vertical pipes or more to launch multiple rockets simultaneously.
