Increased Velocity

| View Cart ⇗ | Info

“The principle of increased velocity as bodies descend from a height, is curiously illustrated by pouring molasses or thick syrup from an elevation to the ground. The bulky stream, of perhaps two inches in diameter where it leaves the vessel, as it descends, is reduced to the size of a straw, or knitting-needle; but what it wants in bulk is made up in velocity, for the small stream at the ground will fill a vessel just as soon as the large one at the outlet.” —Comstock, 1850
