I will call the BS on this one. Nice looking cannon but with a ball valve and a blowgun dart? No way.

I don't see that happening, DWV cannon as well. A quarter is just too strong, I can see a quarter getting bent or dented but not penetrated.

A length of wire has an extremely high sectional density and small impact area, that sort of penetration is more than possible if it's travelling fast enough. Look what the mythbusters did in the deadly straw episode when they fired a length of piano wire straight through a tree, the ply backing and into the cement wall.

Granted, their barrel was much longer than the one in this case, and what doesn't seem right is the fact that the dart shown through the quarter is perfectly straight, I would expect a lot of deformation dpeending on what it's made of.

Agreed, It can be done, but not with that cannon at its present state.

My thoughts exactly.

I'll give it a go with my burst disc launcher when I get home :D

You'd have thought that if it really went through like that, it would have stuck in the board...

I have a blowgun launcher.

I've shot them too fast at a dart board, they bent.

When the front stops, the back wants to keep on going.

That's why this is fake.

Mmm.... I've tried long nails at thick wood and when they stop the back end crumples and often bends right over to flatten against the wood.

Bet he drilled it :P

BS!!!!!
As if the dart wouldn't have just bent and gone off course etc.

It can be done though i reckon.
Maybe we should hold a friendly no prize contest too see who can penetrate a coin with one of their guns.
I'd better use a foreign coin though because i don't want to deface the Queen. :D

Not really an issue, there are countless launchers on this forum that have been demonstrated to penetrate sheet metal easily with the right ammunition.

Yeah sheet metal is easy, but a coin is something different because it's so small, and made from different material, like I can send a small round cylinder of aluminium through a metal tool box, no problem but because it's so big it will just f*ck the coin up, not go through it.

I've got some spare Thai baht coins and some Euro coins I can shoot, sorry to deface your currency JSR :D

Fair comment, but if you can hammer a nail through a coin, then you can shoot one through it ;)
