An Experiment That Solves The World’s Most Important Question: How to Keep Toast from Landing Buttered-Side Down

It ’s not just you . pledge really does res publica buttered - side - down most of the time , and now scientific discipline has prove it — with a simple , but frustrating , experiment that gain an Ig Nobel Prize . Discover the natural philosophy of why the universe hates you . Or , at least , why the world hates breakfast .

Some Ig Nobel Prizes involve simple experiments conducted in a rush . Not so this one . In lodge to leaven that goner acres butter - side - down when it drops , Aston University ’s Robert Matthews get a thousand child to carry 21,000 pledge drops . He proved not only that it is possible to use child toil in such a agency that it seems capricious and unfermented , but that the toast , spiraling through outer space as it drops off the edge of a mesa or a home , will set ashore butter - side - down sixty - two percent of the time . Some experimentation show an even higher pace of buttered floor than that .

There are a couple of ways to get around this . One is a very tiresome push , and the other is a very loyal one . A slow push changes the status of the toast as it goes over the boundary . It will change its original position , tipping slightly , teetering on a slant before it start out the roll over off the boundary of the table . It is now not falling from a butter - side - up position . It ’s falling from a ‘ butter - side - slant ’ position , and that changes things .

On the other hand , launching the toast out like it ’s doing a ski leap will also tilt the betting odds in favor of butter - side - up . This is because a set in motion toast does n’t topple . When a toast go off the edge of a table or home plate , it broadly speaking does so at a speed that allow the conduct edge of the toast feel the unsupported wrench of gravity longer than the following edge does . This causes the leading border to dip while the accompany edge is still supported . When it finally falls , the toast goes into a roster . A toast that ’s been push quickly off a table does n’t roll as tight , because the leading boundary has been pull down for a shortsighted time full stop compared to the next edge . It will dip , slightly , but not roll entirely , in the clip it has falling from the board to the floor , and so it will be more likely to land butter - side - up .

It ’s these three factors that add up to the Law of Toast ; acme , position , fastness of rotation . Flung goner , that ’s been toss into the air , is as likely to land one way as it is another . Toast that you sleepily push off the table , does not have a random commencement , and ca n’t have a random polish . It starts butter - side - up , since no one put their pledge face up down on their plate or table . It ’s pushed at the upper of a human arm reaching for the orange succus . This means that it will be pushed at a speed that makes it potential to tip to a sure degree when pushed off the table , which will have it to go into a roll of a certain swiftness . Since no one ( that I have intercourse of ) has seen a pledge land and equaliser on its sharpness , the toast need not be completely butter up or butter down when it hits the floor . If it has rolled more than ninety - degrees but less than two - hundred - and - seventy level , it will land butter - side - down . It turns out that the average table stature give it time to turn just enough that it ’s between these two angle , but not enough that it can deform past two - seventy degrees and demesne butter - side - up again .

And so this experiment show a rather over-the-top thing . As a civilization , human being have created a situation in which the laws of physics twist against us . If we did n’t use up exposed - faced toast for breakfast . If we did n’t produce tables to be just so high , and chairs that were think of to sit at tables that are just so mellow . If we did n’t blearily launch thing from a table , or a crustal plate , at a sure speed . If any of these things were altered , our breakfasts would be slenderly less probable to be ruined . Instead , we ’ve created a band of circumstances in which natural philosophy makes it probable that we ’ll have a crappy break of day . Clearly the only root is breakfast in bed .
