What you need to prepare
Transparent glass jar with water, tightly closed lid.
Put on the table a white sheet of paper on top of the pencil sharpened end to itself. Take a jar of water and look at the pencil through it, as shown in the figure.
In the Bank the pencil will turn over sharpened end into the other side.
Turn the jar in different directions, bringing it closer to the pencil, then shut. The pencil immediately begin to twist and squirm, as a living.
Put it next to other items and see how they will squirm.
