How can I make exploding cupcakes?

this is for my halloween costume this year (i won't say what it is until i finish it and put up an instructable of my own, haha!) i had two ideas for explosive tasty confections: either using little firecrackers as candles, or putting some type of exploding pellet or capsule inside the cupcakes that would explode on impact. a friend told me about something that may or may not contain mercury, or i suppose it could have been magnesium since it's so comes in little spheres/pellets/capsules that probably contain some of the same ingredients as flash powder, only in a more concentrated form. if such a thing exists, i would just bake cupcakes and squish the capsules into the bottoms of the cupcakes. i'm open to any other ideas. help please!

this is the BEST question I've ever read! 
Sounds pretty epic, Id put firecrackers in them, just dont cook with the gunpowder charges in the pastry.

i think this may be what i'll have to settle for if i can't come up with anything. i'll just have to get really good at timing the fuse length/throw. or i could always leave them and sneak away to startle passerby. _;

Sounds dangerous and possibly contra to the law. How about a scary-halloween carrot?
