The cable tie launcher design is a simple and inexpensive design which is attributed to a water rocket pioneer by the name of Ian Clark. We've taken idea and adapted it to our launcher design in a way which we describe below that should make it very easy for anyone to replicate.
The materials required for this installment of the launcher build tutorial are one roll of Duct Tape, a 1.5" diameter hose clamp, and a package of Cable Ties or Zip Ties.
A good method is to put about 4 inches of ties onto the tape and then remove any extras when you go to mount them to the PVC pipes.
See you next week!
