To So Fill A Glass With Water That It Cannot Be Removed Without

spilling the whole.

This is a mere trick, but may afford some amusement. You offer to bet

any person that you will so fill a glass with water that he shall not

move it off the table without spilling the whole contents. You then

fill the glass, and, laying a piece of paper or thin card over the

top, you dexterously turn the glass upside down on the table, and then

drawing away the paper, you leave the water in the glass, with its

foot upwards. It will therefore be impossible to remove the glass from

the table without spilling every drop.
