Are the stereotypes of balloon home relocation and airborne bicycling really true? Even helium balloons can be affected by external factors like strong winds, weather and climate so don't try any blast-off experiments at home. Exaggerated though movies might be the fact of the matter is that gas balloons do float and do have the stability to carry a crew of people. After all, blimps are a form of gas balloon. (Though zeppelins are not; they are a type of rigid airship)
Science says that just as the heaviest things fall down, so anything lighter than air has the tendency to rise. Since helium weighs 0.1785 grams per liter, it is lighter than air. Case in point: if you were to fill two soda pop bottles with helium and another with air, the one containing helium would weight a lot less than the air bottle.
Wait a minute, hydrogen is lighter than helium. Why don't people use that to fill balloons? They do sometimes, but helium balloons are usually preferred because they are not as flammable a substance as hydrogen. If you're using with hydrogen, know that even the slightest spark could set off an explosion. This is what caused the notorious Hindenburg disaster.
As for as what helium looks like? Nothing. Nor does it have color, an odor, a taste or any identifiable features. Helium is produced from natural gas wells where it is extracted from the crude natural gas stream and purified. At this point helium can be stored and shipped for consumer use, and in either gas or liquid form.
