Rocket Fired without a Nozzle (2011-05-29)

Just wanted to test the fuel burn time, but didn't want to pressurize the motor too much so It was made without a nozzle, just an open tube. The results were unexpected, but understandable. Very shortly into the burn the whole fuel grain was ejected from the motor and shot up about 50 ft before landing just off camera. Lucky water was on standby.
