Will Helium Make A Football Fly Farther?


Since 1970s, when scientists gave a clue that helium filled balloons can fly higher, the theory has remained a myth.

Jamie Hyneman and Adam Savage (hosts for MYTHBUSTERS) decided to test this out..Their prediction was that a helium filled ball would travel farther than an "air-filled" one, since the former weighs less (about 7 grams in total), but... Newton’s Second Law of Motion proved unbeatable… even for the MythBusters.

Reiterating our middle school lessons— Newton’s Second Law of Motion says that the greater the mass of an object, the greater the force (or inertia). Hence," the slightly heavier air-filled football actually pushes through the air with greater force, flying slightly farther than a lighter helium-filled football".
