Connecting up the Water-motor. If you operate the water-motor in the kitchen sink, you can either build a platform as shown in [Fig. 61], to bring the spout of the varnish-can case up to the level of the faucet, or you can set the water-motor in the sink and lead a piece of rubber tubing from the spout to the faucet, as shown in [Fig. 68]. If you use the latter arrangement, slip the lower end of the rubber tubing over a short piece of glass, brass, or tin tubing, and stick the short tubing through a hole in a cork large enough to fit the spout of the varnish-can case ([Fig. 69]). If you raise the water-motor high enough so the faucet will set down into the spout, you can cut a large enough hole for the faucet, through a cork, and then fit the cork in the spout as shown in [Fig. 64].
Another Water-motor. The little water-motor in [Fig. 70] will furnish sufficient power to operate simple mechanical toys.
The Water-motor Wheel. Procure two baking-powder can covers for the ends of the water-motor wheel (A, [Fig. 72]), a cigar-box out of which to make the wheel paddles, and a stick ¼ inch square and 5 inches long for the wheel axle (B, [Fig. 72]).
