Can anyone explain how this works?
If you ask a heavy person to sit in a chair and get 4 people to lift him or her (each person clasps their hands and has their thumb and forefinger pointing outwards, then they place their forefingers under the person in the chair's armpits or the back of their knee (1 person at each part)) then ask the 4 people to lift, they will struggle.
But if you then ask the four people to then put their hands over the person in the chair's head ( hands flat with palm facing down and not touching the head or someone else's hands), then try to lift them as before they have no trouble lifting the person up anymore.
Apologies for not explaining this too well. Does anyone know what I'm referring to? And how it works?
