DIY Nitrocellulose Cannon

Nitrocellulose is just a fancy word for flash paper.  But Youtuber NightHawkInLight has created a pretty simple cannon that he used to fire this flash paper.  It’s all bark and no bite, but that show is pretty impressive, as is the video below.  The entire cannon is very well made, especially the curved hinge.  Actually, everything this guy is doing looks professionally made.  I’m not sure I would have the wires as exposed as that, but hey, it’s not going on my desk.

Ball Bearing Roller Coaster

I remember having one of these in my basement when I was little.  It never worked right, and it was constantly in various pieces, but I always imagined that it would be pretty awesome when it did work.  I drew up plans in my mind of how it could work, and expand, and just be fun, but never got to build them because it didn’t work.

Well, JamJarCollective has an Instrucatble on how to make one of these out of copper wire.

He used heavy copper electrical wire to make just about everything on his track.

And, there’s everything from basic 90 degree turns, to loops, and this sick ass corkscrew that is basically vertical.

One of the hardest parts of it was designing a way to get the balls back to the top of the track.  Because a roller coaster that’s in perpetual motion is way better then one you have to set manually.  Still he used the copper wire for the core, and screw, and the rails, which I say is good, because it keeps it looking nice (i like copper)

And, here is a pretty ace video of it all in action:

Now this has me wanting to figure out how to make it all myself.  Then I want to go 2 steps beyond, and have it go about an entire room.  Except that would cost time, money, location, and skills.  All of which I can get, but not all at once.  So until then, I will have to make due with my imagination, and I think that’s a pretty good alternative.
