shit!
Just when you thought Japan had moved on from its stereotyped image as a nation that creates bizarre, useless technology, it comes up with the Super Great Toilet Keeper (SGTK) – a bespoke toilet designed to save penalties. The football-mad throne is a bizarre, one-off collaborative project between Japan’s leading toilet-maker …
Yeah, I guess you're right that it will automatically handle gravity-induced dip. That leaves a couple of unexplored route to goal I guess...
1 - blast the ball low and hard at the toilet bowl itself, just a little off-centre. The 'saving' ball cannot reach here, it needs to be physically blocked by the toilet bowl itself. So maybe the ball can just deflect off the edge of the toilet bowl and go in
2 - If it's not continuously tracking the ball, putting some (OK, a LOT) of swerve will confuse it
If it IS continuously tracking the ball, a combination of 1 and 2 might do the trick. Hit hard just to the right of the bowl, swerving to just go in off the left part (vide Roberto Carlos free-kick vs France in '97, it's possible to get 2-3 metres lateral displacement off a good swerve).
Damn, where can I find a toilet keeper, I'd like to give it a go!! (Now that WOULD be a great fairground attraction)
Japan: toilet-maker produces something hi-tech, completely useless but fun.
USofA: similar technology but instead of a toilet-maker it's DARPA, Raytheon or such and instead of completely useless it's a new, creative way of killing people. And instead of fun, well it's still fun, but...
