Quote: That would be a neat video put a slabed coin next to a tannerite target and fire at it, see what happens.
I was actually thinking about a 55gal drum with a loose top, and the coin placed in the center, securely duct-taped to the top. 10lbs of tannerite visible through the smallest-possible hole in the side of the can, also centered, should create a nice vertical launch.
Assuming you found the coin after the big bang, I suspect it would survive the launch and descent, but I don't think the slab would have much structural integrity afterward. Even if I'm wrong, it'd make a fun video.
