The Ice Meister Slicer isn't only horribly named, it's also a monster piece of crap that costs $70. For a molded piece of plastic. Anyway, if I haven't (or the nozzle in the pictures hasn't) turned you off already, the sled is ride-able in both the winter AND summer. How? Look at the picture. It comes with two molds you fill with water and then freeze. Attach the blocks to the bottom of the sled, and TA-DA -- why's that kid wearing a helmet? He looks like my roommate the time he shat in the cat's litterbox. Which I may or may not have filmed. Rule 34 baby.
And, to get you in the holiday spirit:
Eddie: I don't know if I oughta go sailin' down no hill with nothin' between the ground and my brains but a piece of government plastic.
Clark: Do you really think it matters, Eddie?
