A Vessel That Will Let Water Out At The Bottom As Soon As The Mouth
is uncorked.
Provide a tin vessel, two or three inches in diameter, and five or six
inches in height, having a mouth about three inches in width; and in
the bottom several small holes, just large enough to admit a small
needle. Plunge it in water with its mouth open, and when full, while
it remains in the water, stop it very closely. You can play a trick
with a person, by desiring him to uncork it; if he places it on his
knee for that purpose, the moment it is uncorked the water will run
through at the bottom, and make him completely wet.
