Hi Jeri et al:

Using my can crusher, if I put a can off center into the loops of wire
which crush it, the can will shoot out of the loops (at a fairly high
rate of speed) and be propelled as well as crushed. Generally, at 4.5
KV, the can will shoot about 10-15 feet. Is this similar to what you're
looking for?

Best, and happy turkey day, to all,
Dave
