Oliver, with all due respect, the wooden thing is ok, although I personally consider it a bad idea to award a winning upon, but you will never in your life convince someone that a solid ice block breaks exactly in half and with a pretty clear cut margin at the point of impact unless he didn't try it on a solid block of ice himself. Solid ice tends to smash in pieces exactly like solid glass. No matter of how hard the shock is, it will still not break in the same point in two blocks put aside, that's even harder to believe. Sorry to say, the ice looks like a bit "cooked" - this means cut with a hot wire and then stuck back with some water and left to freeze so as not to break upon minimal shock.
