Today Myles and I mixed up some more fuel with his hotplate. The hotplate evaporated it so fast that it caramelized and turned a dark brown color. We loaded it into the new rocket tubes with the washers in them and set up the rocket. It hissed up into the air about 5 meters then with an explosion it dropped back down. What had happened is the small washer blew off and the large bore wasn't enough thrust.
Myles also created a mortar by rolling up some fuel and loading it into a longer piece of conduit. This was very cool looking, and so was his scrap bomb, or rather, lots of the little crumbly leftovers wadded up into a piece of tinfoil. This one sent flaming balls in every direction, very cool.
The last engine we lit off had the small washer epoxied to the inside of the larger washer. The larger one was pounded into the tube with a hammer, and the surrounding metal from the tube flared out from the pounding to grip the washer. Just before this, we had lit the second of the duct tape two washer engines, which did an extremely rapid double flip in the air and landed on the ground when the small washer blew out. I was a little scared of this new one because if it had the power to rip ten layers of duct tape, it might have enough built up power to blow up, or something equally as bad. We rammed the motor into the ground and hid ourselves behind an old door. We didn't even look, we could tell what happened by the sound. The engine burned, and then blew the whole larger washer out of the tube. When we went to look, the engine was buried almost 5cm further down into the dirt. Maybe next time I'll make a better rocket to test on since the current rocket has suffered some major damage.
