You know, your experiment inspired a dream. Last night, the heating element went out on my incubator, leaving 6 eggs in the cold. I put them in my shirt while I got the oven up to the right temperature and stuck them in there. Meanwhile, dh rigged up a light bulb in the bator to last it til today when we could figure something a little more permanent out.
But, last night, I dreamed I had to incubate the six eggs in my bra. I'm not well endowed, so it was not going well. Not to mention that in the dream, the eggs were all more like water balloons. In fact, I ended up having two of them spring leaks and squirt a couple feet out, just like a water balloon would.
I wish you the best of luck in your endeavor, and that it works out much better than it did in my dream.
