How helium balloons work…
Helium balloons work by the law of buoyancy. In this case, the helium balloon that you hold by a string is floating in a “pool” of air (when you stand underwater at the bottom of a swimming pool, you are standing in a “pool of water” maybe 10 feet deep — when you stand in an open field you are standing at the bottom of a “pool of air” that is many miles deep). The helium balloon displaces an amount of air (just like the empty bottle displaces an amount of water). As long as the helium plus the balloon is lighter than the air it displaces, the balloon will float in the air.
It turns out that helium is a lot lighter than air. The difference is not as great as it is between water and air (a litre of water weighs about 1,000 grams, while a liter of air weighs about 1 gram), but it is significant. Helium weighs 0.1785 grams per liter. Nitrogen weighs 1.2506 grams per liter, and since nitrogen makes up about 80 percent of the air we breathe, 1.25 grams is a good approximation for the weight of a liter of air.
