I totally just broke a glass ornament with an N-Strike Maverick Rev-6, the greatest thing you can buy for eight bucks. My wife got me one for Christmas this year along with a crap-ton of extra darts, including ones that whistle. I was shooting at her as she was headed for the fridge and I hit the centerpiece on the table, knocking a glass ball to the hardwood floor where it shattered.
This thing rocks on toast. It looks like Hellboy's revolver! It fires up to six shots pretty far. And apparently, you can mod it to make it shoot farther or to make the chamber come completely free of the frame so you can play Russian Roulette. Just search for "nerf maverick mod" on youtube or google.
I think we are going back to the store to pick up a few more of these things for New Years.
