Fastest 1/4 air fitting "rocket" projectile

After printing a bunch of the standard ¼in air fitting rockets, then my first bunch of remixed rockets things escalated a little bit. We shot them around the shop and some broke. We found out the air volume didnt help just lighter weight did. Could even shoot them with it being open. We found out this current design is the fastest we were able to build. You will need a pen, screw driver, quick connect, full size rocket or something to push these into the quick connect. Be careful these are fast and do sting a little at close ranges. Have fun!
