Shooting a block of ice...

Unread postAuthor: Mitchza89 » Fri Feb 15, 2008 12:49 am

Well lads, I tried to shoot a block of solid ice that I set in a beer can (always have plenty of those around :D) and I thought id be able to shoot a 8mm rock through it... To my horror, it did absolute bugger all. Just mearly a small crator 20mm across and 10mm deep.

I really thought it would have blown it up :(...

Ice is quite solid, I fired a water bottle filled with ice at a chair once. It mangled the chair and did sod all to the bottle.

And consider Pykrete, which is ice mixed with sawdust; it is even stronger than ice (approaching the strength of concrete) and it melts slower too. Do we have another challenge thread?

Try making a thin sheet of ice, then shoot it with a largish caliber spud gun, and it looks awesome. It looks kind of like a window shattering.

After I shot the steel and ice slug at the door for my comp vid, I was surprised to discover that the ice was still intact in the cylinder, despite the cylinder being about 1/2 of its original length.

Someone needs to come up with some sort of ice/Pykrete challenge. Maybe something like: "Putting an ice/Pykrete slug through 1/8" steel plate?"

Ice is very strong.....

Where i live, Mother nature was nice enough to cover every inch of every outdoor thing with about a 1/2 inch of ice. I tried to remove the ice from our driveway with a giant metal pole about.... 6 feet long and 3 inches in diameter... and all it did was crack mabey an inch of the stuff away.

i then moved to my Dartgun (156 ft/lbs) and it still just made a "crater" and did not crack the ice at all.

eventually, i just gave up...........

but yes, ice is VERY strong...... (someone needs to make an ice pressure chamber..... NOW)

You're on Benstern. You can expect a video of my attempt whenever spring comes.
