The Magic Tube
Procure a small tube of glass, whose canal is extremely narrow, and
open at both ends; let one end of it be plunged in water, and the
water within the tube will rise to a considerable height above the
external surface: or if two or more tubes be immersed in the same
fluid, the one with a narrow canal, and the other wider, the water
will ascend higher in the former than the latter.
