Up, up and Away in My Beautiful Balloon

I saw this teenage kid who lived among friends and family in a bad part of town. He was jesting with his buddies on some topic that I can't recall. At some point my observer role changed into an active role and we began to talk. He showed me a gun, for some reason, and asked me of the two bullets he had for it would work in the kind of revolver her had. After seeing that the bullets were nothing more than two Bic pen caps with stuff lodged inside of them, I said that they probably wouldn't work in the gun.

Out of no where, we were in the cement-covered playground of my old elementary school and among other people. Equally bizzare, this kid took out a giant helium balloon that was in the shape of a dog. He was trying to get on the thing to fly, I presume, and when he had troubles doing this, I intervened. I told him he had to straighten his legs to go higher and crouch to sink and somehow this all made sense that body shape would affect the pull of gravity on us. (9.8 meters per seconds squared my ass).
