2nd To Last Launch Day

Today we totally pulled together a brand new rocket, due to us forgetting our original prototype. A major change we did do though, was to add a bigger trash bag so that the surface area would be greater for our parachute, slowing down our rockets fall. Our rocket was in the air for a time of 6.08 seconds! That was our best time yet! Another factor of our success is that we added 800mL of water instead of the usual 500mL. We also increased the air pressure in the bottle. We do not know exactly how much psi was added because there was no pressure gauge, but we pumped it until it could not pump anymore. All we need to do now by Thursday is to figure a way to keep in in the air for another 4 seconds.
