Following the recent experiments with the LHC, Professor Hugh Jarse was able to reveal how toasters actually work.
"The question of where did the bread go when the toast comes out has now been answered." Said Profesor Jarse
He went on to explain that a rip that briefly appeared in the space time continuum revealed a 'toast/bread zone' and during observations slices of bread spontaneously appeared followed quickly by the immediate disappearance of a slice of toast exactly the same size.
"We were able to reverse the process and retrieve a slice of bread after placing toast in the toaster and using a reverse phase electrical power circuit"
Despite the remarkable find, no practical usage for the reclaimed bread could be found other than to make toast.
