We launched our rocket three times today. Our minimum time requirement was 5 seconds and after a sad failure of 4.30 seconds on the second attempt, our third trial barely made the cut at 5.07 seconds. We made no changes to the rocket itself, keeping the original fins duct taped to the sides, bottle top as a nose cone, and duct tape and plastic grocery bag as a parachute. For both launches, we set the pressure at 70psi, but with an unfavorable wind of 13mph to the Northeast (courtesy of Honolulu ATIS), our record setting 10 second time last class wasn't even close to being met. However, the parachute did deploy effectively both times. Our first launch was a complete failure. Being the idiots that we are, while Sam was still securing the rocket on the launch pad, Brenna got excited and started pumping...thus resulting in a failure launch into Sam's face--unfortunately not caught on camera :( Luckily, we do have a wonderful picture of Sam and his wet shorts for you to laugh at us with:) Hopefully, the next launch will meet the 10 second requirement...pray for good weather:)
