How many helium balloons does it take to lift a polar bear?
About 45,000 balloonsA polar bear weighs 450 kg, and each balloon lifts about 10 g.
It takes about 45,000 balloons.
How we worked it out
A polar bear weighs 450 kg, and each balloon lifts about 10 g. Standard 11-inch party balloons at sea level, about 10 g of lift each. Real life adds a little friction and waste, so treat the number as a solid ballpark rather than a lab result. The constants behind every experiment are on the science page.
Watch it happen
This was one of the five experiments in It Took #34. In the game you guess first, then the experiment plays out with your number: too few and it fails, too many and it overshoots.
