Gun Fun

Thanks to Say Uncle for this one. Now this is the sort of thing that really gets my blood moving first thing in the morning:


I've built the smaller ones out of a coffee can that make a vortex about 2" in diameter, and they're fun to play with, but this is up in the Werner Von Braun category. There is a possibly higher powered version of this referred to as "compact toroids". This was described as "the nearest thing to the photon torpedo yet" but unfortunately it doesn't seem to work well except in a vacuum. The one I first saw referenced looked like 2 funnels, one inside the other. The example in the link indicates a rod inside a tube, which would have to be very carefully located to make it work,but this seems to have been done.

Coming soon to a battle cruiser near you....
