    ok, lets see how clever you are

    i am going to ask a series of questions. At the end, we will know who is in the clever half, and who is in the thicko half of the congregation.

    question number 1.
    How does a syphon work ? where does the force come from

        How A Siphon Works
        Siphons operate by atmospheric pressure. The container from which the liquid is siphoned must therefore be open to the air. When the tube is filled, the liquid will run out of the lower end. (The greater weight of the liquid in the arm outside the container determines the direction of flow of the liquid.) As the liquid starts to flow, the fluid pressure at the top of the tube is lowered. A liquid always flows from an area under higher pressure to an area of lower pressure. The liquid in the container (under atmospheric pressure) flows up into the tube (an area of lowered pressure). This liquid in turn will flow out the outside end of the tube, again lowering the pressure at the top of the tube.

        Once the flow has begun, it will continue if undisturbed as long as the inside end of the tube remains below the surface of the liquid. The flow can be cut off by raising the outside end of the tube above the level of the surface of the liquid in the container.

        One limit to the use of siphons is imposed by the height to which atmospheric pressure can lift a given liquid. At sea level, atmospheric pressure can raise water to a height of about 30 feet (9 m). At higher altitudes the pressure is less, as is the height to which the water can be raised. Liquids heavier than water cannot be raised as high as water. Thus at sea level, mercury can only be raised about 30 inches (760 mm).

              so far we have three good answers
              but one wont work in a vacuum
              one wont work in space
              and one wont work in the kitchen


              next question.

              Was Einstein actually any good as a patents clerk

                  Are you saying a siphon does work in vacuum and in space (leaving aside how we define "in space")?

                    My question

                    When you ask for parking when making a French Hotel reservation

                    & the bint replies
                    "For the late arrival you have the automate by CB "

                    Does she mean
                    1. Citizens Band
                    2. Something else
                    How fortunate for governments that the people they administer don't think
