The Magic Bell

Fix a small bell to the wire that goes through the top of the
receiver. If you shake the wire, the bell will ring while the air is
in the receiver; but when the air is drawn off, the sound will by
degrees become faint, till at last not the least noise can be heard.
As you let the air in again, the sound returns.
