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.
