exploding wedding cake

I came across this nifty idea on one of my many trawls of the Webiverse. An explosion service by "trained explosives technicians" for your wedding cake. Seriously. 

So perhaps you're the bride and you've had a little sneaky taste and it is a pretty cake but dry and inedible...so you decide to cover your guests in it. This guy in Australia got the beating of his life for exploding the wedding cake all over the bride. Watch the video. Hilarious. You'd better have a cake matching your wedding dress...rainbow cake on a white dress? Nah uh.

The mad people who offer this service, Bompas and Parr, are also master jelly creators. How are THESE instead of a wedding cake, I mean wedding jelly? Wedding jellies?
