Your biggest non-technical hack/discovery
flooha: I'm not really sure if this qualifies as a "hack". A friend and I were riding dirt bikes through the forest and he crashed in a mud hole which was next to a bees' nest in the ground. He was allergic, got stung twice and we were deep in the forest, so we had to get out asap. The bees were swarming around his bike and going 2up on my bike was near impossible. I turned my 2-stroke bike around and pointed the exhaust at the bees and revved the engine. The resulting cloud of oil/gas mix subdued the bees. My friend took the throttle, I wrestled his bike out of the mud and we made it out of the forest as fast as we could.
