I've been wanting to use capacitors instead of multiple batteries to launch rockets. I also want to see how a capacitor driven ignitor works compared to a normal battery driven with clusters of motors. I've been having a couple problems. Problem 1:The switch sparks, which I believe causes significant loss of power, but that's just a guess. Problem 2: When I use an extremely fine piece of wire it pretty much vaporizes. But when I double up on said wire I don't even get a glow. The vaporizing wire leaves a black trail on paper towel but does not get hot enough to ignite the towel. I've seen this on youtube so I know the method works, I just don't know why theirs does well and mine fails.
