Launch 4

Our fourth launch went semi sucessfull.  We were able to get our parachute to deploy properly and have it slow down the decent of our rocket.  We also had added weights at the bottom of our rocket so that it would fall to the ground the right way.  The only problem that we encountered is that the pump came off when we were applying pressure into our rocket.  We plan on pumping until 60 psi and keeping the 500ml of water in our bottle for launch.  We watched Corey and Pono's launch and they reached 10 seconds in the air without a parachute.  I feel that if we were able to apply a lot of pressure into our bottle it could reach up to 15 seconds in the air with the parachute.  I feel that our rocket is ready to be put to the test of 10 seconds in the air by the next time that we launch.
