Blimps, balloons, and zeppelins all fly because they are lighter than air, so they float in the atmosphere rather than sinking in it. Airships are made of lightweight materials and historically have been filled with either one of the two least dense elements there are: hydrogen or helium.
In this WebQuest we are going to look at some of the chemistry behind lighter-than-air flight. The history of airships involves some great chemistry, but it also includes some really bad chemical mistakes, which led to tragic results. This WebQuest now takes you on a lighter-than-air flight through the chemistry behind the successes and failures of airships.
