Helium balloons tend to fascinate adults and children alike (and it's not just the Donald Duck voice thing, though that is a big draw). Learn all about helium and why it floats!

Helium balloons work by the same 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).

What about hot air balloons?They work by similar principles. If you heat up a gas it expands. In the case of a hot air balloon, when the gas inside the balloon expands the extra gas is pushed out the bottom of the balloon, meaning that there are fewer atoms inside the balloon, meaning that the air in the balloon is lighter than the air outside the balloon.

The answer is pretty simple: the helium leaks out. Helium is a very small atom and latex is pretty porous at the scale of a helium atom (if you ever go looking to buy balloons, you will see that there are "helium-grade" balloons, which try to be thicker and less porous).. The weight balance that keeps a balloon afloat does not leave a lot of room for leakage, so once a little leaks out the ...

HowStuffWorks explains thousands of topics, ranging from the flu to black holes to conspiracy theories, with video and illustrations so you can learn how everything works.

But if you’re still committed to using helium-filled balloons to get around, you’d be better off using weather balloons. In 1982, aspiring Air Force pilot Larry Walters had a similar idea. He and his girlfriend bought 42 2.4-meter (8 foot) balloons, along with some helium, and some strong line.

The balloons have two chambers (sort of a balloon within a balloon), the inner one filled with air and the outer one with helium. Valves and a fan attached to the bottom of the balloon can be used to pump air in or out. Adding air to the inner balloon increases the mass and causes the balloon to go down, and releasing air causes it to go up.

Once you get home, rush the balloons inside the cool house. One by one, take the balloons outside, starting with the half-full balloon, and watch what happens. You'll see just how helium expands with heat and what that expansion does to the latex in balloons. Quench everyone's thirst with the refreshing activity on the next page!

This one requires a prize or two. The idea is to sell lots of helium balloons containing slips of paper with numbers on them. Draw a prize winning number out of a drum, and then instruct guests to pop their balloons to get at the number inside and discover if they've won the prize.
