Bottle rocket fins

This concept has not been thoroughly tested yet. If you can successfully make it airborne, please share your findings with me. The idea is to encircle the hose with tape and press it firmly into the base of the nozzle. Next, introduce compressed air into the water rocket from a compressor. Either the device will catastrophically explode or propel itself high into the sky. Epoxy will likely be required to secure the attachment to the bottle and ensure a tight seal.
