Does anybody know why standing on your head and then weighing makes u weigh about 2 or 3 tenths? I have done it many times to make weight, and i never knew why is works. anybody know?

Wow I dont think i have ever tried that one.

lol sry i meant to say weigh 2 or 3 tenths lighter.

i never knew about that one. mabye i should try it somtime.

thanks

A simple phenomena explains it all.

An inaccurate scale.

exactly. i stood on my head in 8th grade, last tourney at JC and i lost 0/10's of a pound, i was on my head until my feet weren't blue, but sickly white.

It doesn't work on a digital scale, only on an old style scale. I would guess the blood moving back to your lower extremities causes your center of gravity to move for a short time, causing the scale to move. Just making a guess though.

i would have to agree that the blood would migrate toward you head and thus making your center of gravity move in turn lowering your weight by a small amount

Are you guys serious? This is the most retarded notion I have ever heard of. Boo, high school science/physics teachers.

You might want to look into an equation that states: force (your weight) = mass (your body) x acceleration (earth's gravity)

It's a simple little property that Sir Isaac Newton came across. Unless your mass or earth's gravity changes, your weight will not change. What you experienced was due to some other factor besides standing on your head.

"Technically", Scientifically, 321a_140 and Zach140 are correct. Good thought on the Newton thing which is correct concerning weight, but do not forget the basic properties of gravity. The force of gravity is affected by two things, mass and distance. What this means is that more massive objects exert more force (pull) on each other. What it also means is that the closer objects are to each other, the more force (pull) they exert on each other. That is why you accelerate when you fall from a plane. Remember, Force=MassXAcceleration, not Force=MassXSpeed. What this means is that the closer you or any object are to earth, the more the earth pulls on you and the effect of distance is exponentially multiplied. What this means is that if you halve the distance, you do not double the force but quadruple it. What does all this mean? What this means is that when you stand on your head causing body material to move towards your head due to gravity and thus farther from earth when you are upright again if done quickly, the body material will be "pulled" less. Consequently, you could and should weigh slightly less. The question then becomes what is slightly, and is it enough to register on commonly used scales. Sometimes it works and sometimes it does not. I have seen it work either because of physics or luck, but I have seen it work and I have seen it work on digitals as well. That is the science which is indisputable and irrefutable (unless one is in denial).

Not in denial (your science is correct) but, I would argue that the distance from your feet to your head and the amount of mass that has changed locations, is way too insignificant to create a measurable (0.2 lbs.) difference in body weight. I am however open to a scientific trial of the above possibility. This would have to be done under controlled conditions. My questions for anyone who claims this has worked for them is what else transpired between the first weigh in and the second. You can easily lose 0.1 lbs. in one hour by doing almost nothing at all (assuming no fluid or solid intake). Let's put it to the test!!
P.S. - I commend you for an excellent response. (Some people think that only dullard oafs visit this forum.)
P.P.S. - I see from your profile that you are a teacher. I would have been more impressed if you were a student. :p Nevertheless, I am glad we have teachers/coaches of your caliber.

I'm with Jim. While WSEWC's analogy may make a difference on a much larger scale (pun intended), a 112 pound wrestler will not displace enough body fluid to make a .3 lbs. difference. So I stand by my previous statement of "this is the most retarded notion I have ever heard of. Boo, high school science/physics teachers."

poop. or gag urself

I have seen this work myself, as i have done this myself, it works for some reason, the most i've lost is .2lbs but i've seen it happen the kid is .1 over and he stands on his head for a while then hops back on and is right on weight then steps on after weighing in and is .1 over again? not sure why/if it really does work but kinda interesting

Thank you for commending me on my very excellent reply, Mr. Gaither. You are correct, I am quite crafty. I am so smart, I am sure that I could best the great Prant Garker in a spelling bee. As for pegging me a teacher though, you are, alas, not correct. Although I wish I was, as that is what I aspire to be. Or at least that is what I aspired to be until some goof off from the school of rock told me that those who can't do, teach and those who can't teach, teach gym. I am just a lowly student/athlete who happens to be a 4.0 who is also aspiring to be valedictorian or at least salutatorian. But I did study under a great teacher, Sir Isaac Newton, I met him on an excellent adventure with Bill and Ted. Your kind words though Gaither Man have inspired me to perhaps pursue my dream once more of being a physics teacher/wrestling coach. And do not boo physics/science teachers you Mr. dingbat you because the science behind the weight loss phenomenon is indeed still correct. I myself in my own response stated that the difference might not be enough to register but it is still a difference you Mr. dingbat you, did you not read my response in it's entirety. Regardless, I have seen it work and it should work due to the science. Again I state, I do not know if it happens because of luck or totally due to the laws of physics or perhaps even some other undetermined anomalies, but I have seen it work and on a digital I might add.

At least you don't want to teach English.

Your posts are getting a little wordy WSEWC.

And by wordy I mean way too long and boring to read. Let's shorten it up man.

Here is the ultimate solution, move the scale to the second floor of the building. That is much more of a difference than moving aobut 1/8 a pound of blood 5 feet (from your feet to your head). Will either method change how much you weigh, not any measureable amount. Why did it work for those other knuckleheads- because they were probably too dizzy to stand still. If they were using an old school scale the movement would cause the scale to "Break". If it was a digital scale, you have a crappy scale.

When I was cutting weight, I always wanted to weigh in at Denver, since it is a mile higher than where I used to live. I thought that would make a difference. The thing I was not accounting for is the certification of the scales. They are supposed to be certified with precise weights, which if they were all made at the same place should weigh the same. The scale in Denver would be adjusted so that the 50 pound weight would cause the scale to read 50 pounds, just like the scale at sea level. The realization of that caused a profound sense of loss. I then moved on to deciding which organs I could live with out, Appendix, wisdom teeth, 1 kidney, etc.

Oh yeah, I am a science teacher.

Boo Junior High Boys Basketball Coaches!!

Losing weight whats that?? Yea its kinda nice for me I weigh in at 97 with my cloths on I dont have to worry about cutting weight.
