Making Water Flow "Up Hill"
1956
I assembled glassware and tubing to connect an upper water
reservoir (funnel-shaped) to a lower, air-tight bottle, which had a
flexible tube going from it to an air-tight bottle full of water.
The falling water compressed the air in the empty lower bottle,
forcing air up into the upper air-tight bottle of water. Water in
the upper bottle was thereby forced up hill through a tube that
carried the water to an elevation equal to the fall of the water
from the water reservoir. Thus I made water "flow up hill," using
only water from the same elevation as the water which "flowed up
hill."[Top]
