(10) 1/2" PVC Pipe Mandrels

Set of (10) 1/2" PVC Mandrels

We recommend these for use with groups to speed the build time and make sure the paper rockets fit the launcher.  Getting the correct fit between the paper rocket and the launch tube is important.  Too loose, and you loose performance, too tight, and your rocket may turn to "Confetti".  These are 12" lengths of 1/2" PVC pipe the same diameter as the launch tube on the launcher.

NOTE: These are used to form the paper templates to the proper size, they are not launched, and are reused.
