The first video is our launch 2 and our second video is our launch 3. For launch 2 we had added fins and a parachute to our rocket. On our first attempt the rocket head ended up flying off and no deploying the parachute. We had attached a golf ball to the top in order to have it fly off and pull the parachute. We also had cut small slits in the bottle so that air would rush in and deploy the chute on its way down. On our third launch we cut the slits bigger and put a piece of plastic to funnel the air into the hole more effciently. We also added a weight to the bottom of our rock so that it would fall towards the ground in the right direction. Although our third launched didn't go as planned the chute only didn't deploy because it was stuck to a piece of tape. I believe that if it wasn't for the tape out parachute would have deployed effeciently because it was half out expect for the part stuck to the tape. Our bottle seemed to stay in the air for about 4 seconds without the parachute. Hopefully with the parachute we will be able to gain 6 more seconds to our time in the "AYER."
I thought it was really original of you guys to cut small slits in the bottle— I would have never thought of that! Actually, that's a great concept... let me know how that works out. But I think that if you guys cut the holes too big (like bigger than a dime) it might actually end up damaging your rocket instead of helping it. Anyhow, good job today!
