TIE DOWN YOUR LOAD !!!

I was told by a volunteer fireman that full air-packs were lighter than empty ones.

Who's correct? I have no idea now. But for some reason I am leaning toward what the fireman said.

Sounds like a it's time for an experiment anyone got a truck inner tube they can weight deflated> and then air it up with say 30 lbs. and weight it,
or is this a job for the ((((-Myth Busters-)))):thumbsup:

Its not a job for mythbusters, a full scott air tank is heavier. An inner tube with more than 0 psi in it is heavier. This is 2000 year old archimedes type stuff folks.

Ah Yes! but still an interesting subject to argue over eh!

for instance: let us take 2 balloons, fill one with air the other remains flat,
with one in 1-hand the other in your other hand, tossing them into the air at the same time, which one remains in the air? and which one immediately falls to the ground? Now we Know the 2 balloons weigh the same when empty and we are to believe the air filled balloon is supposed to be heavier, Right? or wrong! but yet it's the air filled one falling slowly to the ground, ah yes! but now we must consider it's Mass and how it comes into play, the air filled balloon is larger therefor has more resistance to the outside air surrounding the balloon
so why does the weight of the air inside the balloon not force the balloon to plunge to the ground regardless of its mass could it be because the air inside the balloon is equal to the air outside surrounding the balloon and could it be that the only reason the balloon drops at all is because of it's weight of substance, same as the unfilled balloon,

Ah but you forget that you filled the balloon just after eating that garlic/anchovie pizza thus filled it under pressure with heavy air. Now if you would chug a couple beers and then fill it with belchanese air it would float like a butterfly:laughing:

Seen a D5 dozer on a tri-axle equipment trailer behind a Ford 8000 dump truck not tied down at all today. He was doing about 45 in stop and go traffic by the mall on my way hone from work today.

I'm a professional firefighter. Would that be me that you agree with? Any scuba diver will tell you that empty scuba tanks are more bouyant than full ones, despite the fact that full ones displace more water than empties. I also doubt anyone could tell be lifting how much air is in a truck tire, but the guy is either too strong to make fun of, has a great poker face, or both. I think bigtiller's firefighter hasn't figured out the progression of fatigue yet! MikeD74T

I think we can put this debate to rest. My firefighter friend must have been mistaken. When he told me that, he had been on the department for about 12 years and of that 12, at least four of them were with the rescue squad.

I have been keeping my air pig in the shop full of air all these years because he said it would be lighter that way. Live and learn I guess.
