This is a pretty old trick but still very impressive. If you take a wooden ruler and lay it on the edge of a table and try to break it by bringing a force down on it, the ruler will just fly off of the table. But when you lay a piece of paper on top of the ruler then the surface area that the air is resting on is much greater than it was when it was resting on the ruler alone. So with all of the air pressure on the newspaper, the ruler is unable to move when quick force is applied to it, causing the ruler to break.

Give this trick a try, but be careful, the ruler can fly up and hit your face or hit an object in the house.

The reason i blurred out the newspaper is because logo's and businesses appeared in those ads.

I believe the REAL question here is...did you finish the puzzle on the newspaper?

Thumbs up if you saw this experiment on Mr. Wizard's World on Nickelodeon back in the mid-1980's lol. I doubt I get many...

With the ruler alone, while it is set down and you hit it, air has a bit of time to get under it. preventing it from breaking. With the news paper, it create an even better air-tight seal, and the ruler doesn't receive enough time to get air under it, so it breaks.

Atleast, this is what I believe happens

[TheJasonX1990]

Air pressure is usually at a constant of 3 lbs, when he did it with no newspaper, the ruler was aerodynamic enough to break it, that and there isn't enough surface area to hold it down with air alone. However, when the ruler had a newspaper on top of it, air pressure only affects the top part of the paper, the bottom half was nothing but a vacuum creating a suction effect. Holding the ruler down with about 3 lbs which if hit hard enough is good enough to break the ruler.
