Scientists seem to have found the answer to a question that has troubled them for a long time.
To find out why the toast always falls butter side down, researchers from Manchester MET University dropped 100 slices from a table two and a half feet high.
Scientists say that the answer lies in the height of the table. The experiment revealed that after the toast is dropped, it falls off the edge and has time just enough to perform a half somersault before it lands.
Since the side that has been buttered is naturally facing upwards, that's the side which actually lands on the floor.
'The upshot is that if you want to ensure your toast lands butter side up then you should invest in a higher table approximately 8ft high that allows the toast to rotate a full 360 degrees,' researchers said.
