The Moment of Truth

 

Okay, so this was the moment of truth for every group in class today. The final launch was due and the time to get was 10 seconds. This is where, all of our work really paid off. So, as a group we fixed some of the modifications on our rocket, so as to avoid mishaps from last class, like cutting down the fin size and making sure that our parachute was secured to our rocket. With our rocket in hand and our confidence high, we went out to the field to launch. On the first trial, we launched with a little under 800ml of water, and 20 pumps (which is around 50psi). This actually got us all the way to 9 seconds on the first try! This boosted our moods considerably, so we kept going to try for 10. Eventually, the parachute came off again, so we had to repair it. We launched a few more times, until finally (mostly thanks to some heavy wind) our rocket sailed through the air, parachute deploying at its apex, and floated down the hill towards ʻAkahi. Thankfully, it avoided the roof, and netted us 10 seconds of air-time! So, we'd finally done it and now, hopefully, we'll get a good grade for the rest of the project. Well, at least it was really fun!

P.S.: Good job to everyone else, too. Let's beat period 4 for average time!
