Measure three 1 foot sections of PVC and one 6 inch section and mark them for cutting.
Using a PVC cutter (great tool) or a saw, cut your PVC on your markings. You should now have three 1 foot sections, one 6 inch section, and a long remainder piece.
Add two of the 1 foot sections to opposite sides of the + connector. Then add end caps to the open end of both of those pipes.
Plug the 6 inch section of PVC into the + connector and add the L fitting to the other end of the pipe.
To finish the structure, add the last 1 foot long pipe to the L connector and the long pipe to the last end of the + connector. Make sure the L is facing up and perpendicular to the rest of the structure.
Place the 2 liter bottle over the end of the long pipe and secure it with tape. Make sure to use enough tape to hold it on well and seal the connection.
Using an extra piece of PVC pipe (or you can remove the upright launch tube from your launcher temporarily) roll a sheet of paper around it, but not too tightly. Secure the seam with a strip of tape.
Try adding fins to your rockets. How does changing the angles of the fins change the flight? How does a bigger bottle (like a milk bottle) change the rocket’s flight? Try building an altitude tracker to see how high the rockets fly!
