ideas or methods of splosh delivery would be a good ide, rather than the standard pour from bucket etc
one i used was the tesco easy open 1kg custard cartons (don't know if they still do them????)
hold it on its side in one hand with the easy open end towards you or sploshee then squeese or slap really hard with the other hand and you get a face or target full of custard
you could make regular packets easy open by weakening them in one end
i was thinking of lining some up in the road and waiting for a car or lorry to run them over and get sploshed that way
going to a park at night and placing a large mound of wam stuff at the end of a slide and comming down it with legs wide open is a great one, removal of knickers first is a must

some custard on the slide run increases velocity!
if you are into facial pies, try tieing some to a bar, or other thing above head height, have then dangling face high, then run like hell towards them, having several in a line is balm balm balm balm great LOL
if you know you wont be disturbed or have freinds to watch over then you could make a few different obsicals like that and run, jump and slide throgh a lot in a short space of time
that should give some producers a good idea

warning, foxes do like custard and have followed me through a few parks and streets while covered in custard, i know they don't normally attack but i did get really freaked out one night as the little fuckers were following me within the bushes and i wasn't sure in they thought about an ambush
