Unless you have seen the animated movie UP ‘Can a house fly?’ is a funny question. The movie with the Boy Scout, Carl, and the grumpy old guy had quite a few people asking could a house fly?
We can do the maths, mathspigs! But why do the maths if someone has already done the hard work for you?
Unfortunately, all of their calculations are in American units but we can use their calculations as a guide. We will not include the weight of the balloons or string and we will assume the balloons are spherical so the answers are approximations and add a few more balloons to make the house & balloons more buoyant than air. Here is the information you need:
Can you fly?
We know humans can fly using helium balloons as 2nd July 1982 Larry Walters tied 45 weather balloons to a garden chair and flew to an altitude of 4,600m (15,000 ft). He carried a bbgun to shoot balloons for his descent but only hit a couple and dropped the gun. He flew for over 45 mins and was arrested on landing. Larry Walters link.
While I would advise mathspigs against such a stunt it is interesting to calculate how many balloons you would need to fly:
Don’t forget to add your weight in Kg.
Here is one of my favorite HOT AIR balloons called, wait for it, THE HOT HARE BALLOON.
