Eggy bread
I'm not sure if this actually counts as experimentation, since I had absolutely no doubts about the eventual outcome when I started, but when I was about 4 or 5 I decided to treat my parents by making them breakfast. Having seen them eating what I later realised to be poached eggs on toast, I attempted to replicate the dish by cracking open two eggs, putting each on a slice of bread and putting both slices in the toaster. Result: one fucked toaster.

Credit to my parents though, as instead of giving me a bollocking, they rescued the situation so adroitly that for years afterwards I genuinely believed I was the inventor of French toast...
