The Known is finite, the unknown infinite; intellectually we stand on an islet in the midst of an illimitable ocean of inexplicability. Our business in every generation is to reclaim a little more land.  -T.H. Huxley, 1887




Ed Marriott and I had made a large fleet of rockets which we intended to launch. We decided to do this all on one afternoon. Here's the fleet.



We lost or broke most of them. So here is some videos, First to prove that we can and know how to launch a rocket successfully



Now for the fun stuff... All the mishaps. First up, I had made a rocket that was basically a rocket motor with fins glued to it. I thought it might be stable, guess not. You will also notice that it explodes at the end. I had capped the front of the rocket where the parachute charge usually is released. We forgot about this.



The next rocket was also an experimental one. I used 4 rocket motors in parallel ( or clustered in official terms) Usually this is hard, you need to fire all the motors and at the same time. We proved this point. Only 2 motors fired off.



We then launched this rocket again with only the two motors remaining. This one is sweet.



I had a little foam airplane that I strapped a rocket engine too. We tried that out a few times with different configurations.





Airplane Spin


And lastly, with pieces of broken rockets and a few left over engines I whipped this rocket together. It had three stages and was made of two rockets all taped together. Two motors are in the bottom rocket and one in the top rocket. What ends up happening is that the first motor fires and the rocket is very heavy so it doesn't go too far up, it then lights the second motor, this motor wasn't stuck in good enough so it flies through the rocket, pops the top off and cruises around. Very exciting, Don't try this at home.



That ended our fun for the day.


Here is a video of the launching of the rocket that got me my level 1 license.

Here is another video, not of my rocket but of Tims.
