MAGIC TRICKS - SCIENCE FACTS

SCIENCE LABORATORY DEMONSTRATIONS AND EXPERIMENTS ARE PRESENTED AS MAGIC TRICKS. THE SCIENTIFIC PRINCIPLES BEHIND THE TRICKS ARE THEN EXPLAINED. STUDENTS LEARN SCIENCE WHILE ENJOYING THEMSELVES. THIS PROGRAM SHOWS THAT ENTERTAINMENT AND EDUCATION ARE NOT MUTUALLY EXCLUSIVE.

Great Observation. I sometimes simplify the explanations of my demos to make the concept understandable to people with less scientific understanding, hence your response to me. You have aq greater knowledge.

You have pretty much summed up the answer. Air pressing down upon the newspaper approx A back of the envelope calculation shows that there is about a ton of air pressing down on about 1 square foot of flat surface. Assume that the new2spaper surface is 2 square feet.

Its cool how much things in the world are tied in to science. Great video!

Thanks for the kind words

I'm suspicious of the idea that air pressure is responsible for breaking the ruler since air pressure on the newspaper is acting in all directions, not simply from above. Perhaps instead the amount of air that needs to be moved when the paper is lifted creates additional work since the newspaper is not very aerodynamic. Either way, I think it would be incredibly interesting to see this done in a vacuum. Doing this under water while changing the water pressure would be interesting too.

Suspicion is a good thing. This is what allows science to move forward. There is a very little air under the newspaper as it is resting atop the table. Consequently there is no equal air pressure on the opposite side of the newspaper. Since there is hardly anything pushing the paper up from underneath, the main force is air pressure from above, which allows the paper to stay flat enough until it breaks.

Kinda funny that his mention of "Nintendo" is relevent again today - the video was probably made before the "PlayStation era"

I wish he was my science teacher...

isn't science wonderful?

Just learn the science behind the magic and the rest or your life will be boring. Dont listen to this guy, keep life a mystery as long as possible, stay stupid.

Heresy and witchery of the worst kind!

SCIENCE = NINTENDO HOLY CRAP

This guy rocks.
