Just got one of those cereal containers and it's awesome. They really do fit pods perfectly (I can hold it upside down and it stays in). I think there will still be spillage on disconnection, but it'll be easier and faster (the filling not the spillage ). Only cost 2 quid at morrisons, why the hell not?
I tried the cereal container thing and it works a treat. If you play Xball lite and your podbiatches are under a lot of pressure it really helps speed the filling up so you have more time to wipe players down and clean lenses etc in that short turn around.
