Slicer: Bringing sledding to people who don't have snow

Sledding is an amazing outdoor activity. At least, when you're not falling flat on your face. But, what about the sledding in the summertime? Well, many sledding enthusiasts were left out in the cold on that one. That was, until this marvelous invention arrived. The Slicer looks like a normal sled, except it has removable ice trays on the bottom. You fill the trays with water, stick em in your fridge, and there you go! It's like your sledding on snow. I would think falling on your face hurts a lot more without a cushion of snow though.
At $70 it may not be too bad of a deal. Oh, and it can also let you fall on your face, I mean sled, in the winter.
