How much does it cost to install a central air conditioner per sq foot
There is really not much you can do about it.
you will probably will require 10 AC 5000 sq feet room
this is a pretty good party trick. tip your head back and pucker your lips, then blow out to make a strong stream of air straight up. then place the ping pong ball in the air stream and it will float! tip: keep the air stream strong and constant and you should be able to keep it up for 4-5 seconds before gravity takes over.
you can.
you need a 100 foot tall crane with thin wires in broad daylight
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
None at all.
No a train does not float in the air, no train does.
things float in air because of density
If it were, it would float in air. Does it float in air? There's your answer.
None, since there can be no conversion.A cubit equals 1.5 feet so a cubit foot equals 1.5 square feet which is a measure of area in 2-dimensional space. The amount of air breathed requires a measure of volume in 3-dimensional space. The two measures are different and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.

The float has air in it.
Everything I can find says that a cubic foot of air can lift about 62-63 lbs.
Only in water. The air from your mouth is the same density as the air in the room- they will not float in air.
Helium is lighter than air. So it will float in air.
