Why your toast falls butter side down:

Scientists finally uncover the reason... and it's all to do with the height of the table

It's a sticky issue that has plagued scientists – and breakfast tables – for decades.

But now researchers claim to have found the definitive answer as to why a piece of toast always seems to fall buttered side down.

Apparently, it’s all to do with the height of the table. They claim that after it topples off the edge, the toast only has time to perform a half-somersault before it lands.

The phenomenon has baffled scientists and the public alike for almost 180 years.

It was discussed as long ago as 1835, in the New York Monthly Magazine.

I'm reminded of this :

The Cat & toast.

When a cat is dropped, it always lands on its feet, and when toast is dropped, it always lands buttered side down. Therefore, if a slice of toast is strapped to a cat’s back, buttered side up, and the animal is then dropped, the two opposing forces will cause it to hover, spinning inches above the ground. If enough toast-laden felines were used, they could form the basis of a high-speed monorail system.

1. The second proposal is even better:

I’ve been thinking about this cat/toast business for a while. In the buttered toast case, it’s the butter that causes it to land buttered side down – it doesn’t have to be toast, the theory works equally well with Jacob’s crackers. So to save money you just miss out the toast – and butter the cats. Also, should there be an imbalance between the effects of cat and butter, there are other substances that have a stronger affinity for carpet.

The probability of carpet impact is determined by the following simple formula:

p = s * t(t)/tc

where p is the probability of carpet impact, s is the “stain” value of the toast-covering substance – an indicator of the effectiveness of the toast topping in permanently staining the carpet.

Chicken Tikka Masala, for example, has a very high s value, while the s value of water is zero. tc and t(t) indicate the tone of the carpet and topping – the value of p being strongly related to the relationship between the colour of the carpet and topping, as even chicken tikka masala won’t cause a permanent and obvious stain if the carpet is the same colour.

3. And orange marmalade only makes it worse!

It still only does a half flip. But now you've got sticky, sugary, yummy stuff on your floor. And you don't get to eat the toast.

Nota bene: It's a well known scientific fact that orange marmalade cancels the five second rule. You drop it? You're done.

8. When brushed off a table, the MythBusters also found it would flip one half rotation.

They briefly mention that in the clip you showed. For the big test, they changed to a straight drop test. In real life, toast falls off the edge of table far more often than it gets dropped straight down. (OK, I have no proof of that. It just seems so.)

9. Wouldn't the adhesion of toast to cat need to be greater than weight of toast + cat?

Otherwise, the toast would just be ripped off the cat's back. And to support a monorail? I know that cat fur sticks to everything from experience, but not with enough force to support a train. OTOH, it would create jobs. There used to be people who lubricated the wheel bearings of trains. Cat butterers would probably be a fairly similar position - dirty, dangerous, but very important.
