Dangers while lowering a load using the Hi Lift (farm) jack - violent handle recoil

Dr. Tejas Kothari, a certified I4WDTA trainer and Offroad Junkie demonstrates what could happen if your hand slips off the jack handle whilst lowering a load and your head or hand comes in between. We put a coconut to show the damage and the result was very scary. Please do not try to replicate this experiment yourself.
