Explosion!

I experimented with baking cake mix inside eggshells today (the idea being that I'd take them for my friends' children as a surprise, and they would open the egg and be surprised to find cake inside). I've never used cake mix before, and it's clearly got a lot of raising agent in it - it expanded considerably! Luckily I managed to salvage the eggs from this mess, and I'm pleased to report they went down very well with their intended audience.
