I used to do this with friends almost 20 years ago in school, thank you to remind me! The only and unhealthy difference is that the person who´s going to be lifted had his head pushed heavily down for the lifters for about 10 seconds. It was part o f the trick, to "move the gravitional center"...amazing 9-10 years old kids explanations...
Well, it always worked, and the lucky one almost flew above our heads before turns heavy again
