A SIPHON.
A simple glass siphon can be made by taking one of the above tubes and heating it at a point about one-third of its length from the end, till the surface appears a rosy red; then carefully bending it over the round part of a clothes-pin, till the two ends form parallel lines.
A simple experiment with the siphon affords considerable amusement to the little folks, and is well worth trying. Take two tumblers, place them side by side, and fill one with water. Now fill the siphon with water and place the longer end in the empty tumbler, and the shorter one well down in the water of the other. Immediately the laborer will begin to work, pumping water into the empty vessel, and will not stop until he has reduced the water in the full tumbler to a level with the end of the tube.
