At what point does bread become toast?

This thread is toast!

Ok, but when did it happen?

Late for work one day, I took my battery powered toaster with me and as luck would have it, the toast was done as I was in the lift going up to my 50th floor office.

The toaster pinged as normal, the eject mechanism fired but the toast never appeared.

What happened?

You’re a midget and you used your umbrella to push the button. No, that’s not it.

You forgot the toaster outside the elevator?

Nitpick opportunity taken: toast preceeded sliced bread.

Even if you stretch sliced bread to mean sliced by knife (when we all know that the idiom is actually specifying bread pre-sliced at or before purchase), it is possible to tear off a chunk from the loaf and toast it with a toasting fork over a fire.

Toasting fork.

When charring has occurred, though, you know it’s not toast anymore.

There is a thin line between benzene rings and perfectly toasted toast.

Does your toaster dial go up to 11?

Great. Not only was my lame joke not funny, it was also conceptually flawed.

There is a simple explanation. A millisecond after the toast was ejected, the elevator suddenly accelerated upwards at a velocity greater than or equal to the velocity of the ejected toast. Because of this, the toast remained in the toaster.

True fact: If you’d been in an airplane when the toast popped out, it would have splatted against the rear wall.
