re: #83 Bagua

The Police Chief said they called someone at university IIRC who told them the balloon could lift 80lb and the boy was 37lb.

I saw that. I believe the police were given bad information. There’s no way a balloon that size could get a kid off the ground.

The Mythbusters show has done several segments involving lifting a person with helium in various containers. In one, they tried to get a (four year old?) girl off the ground with a cluster of large-size party balloons, like you see at fairs.

It took over eight thousand of them to get her just barely off the ground. The cluster was enormous; it nearly filled the airplane hangar they were using.

The same has been true on other segments. The amount of helium needed to get even a small amount of weight off the ground is enormous.
