A dessert trebuchet, you say? Sounds fantastic!
However for the distances involved, I'd probably need something actively driven like a catapult rather than good old gravity-fed trebuchet... Still, sounds like a splendid day making one hell of a mess!
Or we could just mail stuff. I'm working on a mousse that would fit great into a courier bag!
And it's just a shitty 16 bar loop?
