Equilibrium of the body with an object
Take any object – a pencil, a ball, a chair, a book, a table, a file, a sheet of paper, etc. Try to find as many ways as possible of holding the object, using every possible relationship of body to object – sometimes holding it close to the body, sometimes at a distance, sometimes above, sometimes below – whatever you want to do and can do. At the same time you are constantly changing your body’s position in relation to the floor: every part of the surface of your body must touch both object and floor in every conceivable strange and unaccustomed position. A postage stamp, a pen, a book, a shoe, a postcard, a telephone . . . anything will do. The important thing is to study the body–object–gravity relationships.
