its cool and ridiculously simple!
the main weight (hammer head) hangs directly underneath the very end of the ruler, so past that point the weight is minimal and the ruler just needs stabilising, and the hammer handle does that job nicely. also the string will have to be almost vertical

!!UPDATE: I was wrong, physic is a word, it just means something much, much different from the common usage of the word "physics". A physic is a medicine used for purging; a common example being laxatives.

That said, in a certain sense, "physics work" is a correct sentence, in that laxatives do typically deliver on their intended purpose. It`s just not a phrase you would really want to use in this particular context.

Thank you Evelond - someone had to do it.

Also, not to be an ass, but it`s "physics works", not "physics work". There`s no such thing as a physic, so the S does not make it a plural. Sorry, it`s a pet peeve of mine. Interesting post though, its a fun experiment. Same principle as those little bird toys that balance on the beak and have weights hidden in the wings.

"It`s photoshopped. I can tell by the way the--"

Hello, I am sorry to inform you that Evelond just had a massive stroke of stupidity. It is very unlikely he`ll recover. As head of the worldwide Board of Common Sense, I urge you all to take Evelon`ds unfortunate accident as an example as to why you should not take part in dangerous activities such as asshattery.

We now return to your regularly scheduled IAB comments.

That was awesome.... Oooo... Just thought of this:

HEY DUDE PUT YOUR HEAD UNDER HERE!

WHY?

CAUSE THIS HAMMER CAN FLOAT AND WON`T FALL!

ORLY?!

YARLY!

30 seconds later.....

VROOOOMMMMM. Hospital time.

8 pounds per square inch right? You can also snap a ruler with a piece of newspaper and a a good karate chop.

"It`s like those toys that you balance on the tip of your finger and they "magically" stay there."

=O wow, that surprisingly simple statement immediatly enlightened me
thanks, opie
i have one of those toys in my house for years, a green bird
never ceases to keep me busy

Its called center of gravity, since the hammer is tilted to one end and the other end is close to the middle of the ruler, 80% or 90% of the weight is towards the hammer head, making a counter balance. If he was to level the hammer with the ruler with two rubber bands and then try to balance the ruler on the table it would simply fall to one end. Or this is just fake.

Cool, but still not gonna trust a giant hammer with a bridge.

The REAL trick is how he set that thing up so that the string wouldn`t slip and destroy the meticulously-calculated balance.

@masticore, yeah, that sounds hella easy
geez, i should pay more attention in science class
too bad the monotonous voice of my teacher immediately puts me to sleep

its really self-explanatory if you can do free-body diagrams. The center of mass of the ruler, rubber band, and hammer is under the table. The contraption stays in place by the inward internal force of the band and the outward internal force of the contact point between the ruler and the hammer. The band lifts the hammer upwards, while the contact point provides a moment to stop the hammer from rotating.

If you want to do the analysis yourself, draw a free-body diagram of the hammer alone, and sum forces vertically and moments about the band, set them equal to zero (since it isn`t moving), and solve for the forces. Fairly straightforward. Do the same for the ruler alone too if you`d like.

WHOA! science has just blown my mind!
someone care to explain that?
@elhadji, my God`s right there, holding the other end of the stick up
that`s how it`s balancing like that
you can`t see him because non believers are SHUUUUNNNNNED
xP yeah, i went over board there

Dainty; It does work, it`s all about manipulating the center of gravity. Google "center of gravity tricks" and I`m sure you`ll find tons of explainations.

Dainty : i went upstairs and dropped it on my wood floor. it made a huge dent and little cracks around it.
