The catch is, I'm baking with aluminum foil and plasticware. Which means I can, essentially, create cake of any shape/size, then freeze it, and set it up with lots of hard frosting (or even toothpicks, if the situation requires) so it'll take whatever form I give it.
Problem is, I can't think of anything 'good enough' to do. I need something cool and CS-related that would be good to cakeify.
The second option (which I'm leaning towards) is to make your standard layer cake, then place it on top of my 4' tower of cups. For the judging, I'll loudly proclaim "STEP BACK, GENTLEMEN, SAFETY IS NOT GUARENTEED - I HAVE ONLY DONE THIS ONCE BEFORE" then pull out the bottom cup, causing the whole tower to crumble, and either landing the cake nicely on the table or making floorcaek.
Ideas/Opinions? (or else I'll post a thread in the lounge about it)
