So you know why does toast always seem to land butter-side down? Well, Scientists have unveiled the mystery of one of science's most enduring questions.
Food science expert Professor Chris Smith and his team dropped 100 slices of toast from table height in lab conditions to calculate the formula, highlighting that the way buttered toast lands isn't just a case of luck, Metro.co.uk reported.
In the experiment, which was commissioned to mark the DVD release of The Big Bang Theory season 6, the researchers found that the effects of gravity and drag combine to influence the event.
Therefore as the bread falls to the ground it only has the opportunity to achieve half a rotation before reaching the floor, thus landing butter-side down.
