It's a classic video moment. If and adult had been standing and shooting, you would never have gotten to see how he gradually lost his balance. We have our kids birthday parties at these special gyms or party centers. They have all kinds of cool activities for the kids. One of the things they do is play with a parachute.
Most people just poiunt down and shoot.
The result is lots of parachute and very little kids. Not very interesting. Next time try getting down low. If the room is bright enough, get under the parachute with the kids. A burning candle and flickering lights make great transitions.
