When I was a very young lad, I told my friends I could train bees. I would catch them in a jar, cover it and let it sit in the sun. If I remember correctly, it was about 15-20 minutes. The bees would get exhausted from the eat or lack of oxygen. Not sure which. I would uncover the jar and let them crawl on to a flower. It would take some time before they had the strength to fly away. So, I would walk around and show my friends my trained bees. After a couple of times, I figured out about how long it would take to get their strength back, so I would instruct them to fly away. timing wasn't always good, but effective.
