Get a thin bit of plastic tube and a glass of water, start the siphon by sucking on the open end with the other under the surface of water, then move the open end up until siphoning stops. Raise it higher and the water flows back into the glass. The outlet has to be lower than the inlet.
You cannot siphon water from a lower place to a higher place without external assistance. It defies the laws of thermodynamics. You must use an electrical pump or some other means to assist the water.
Water in a siphon can flow uphill too, as can a puddle of water if it's moving up a dry paper towel dipped in it. Even more curiously, Antarctica has a river that flows uphill underneath one of its ice sheets.
Workers dug winding channels underground and created networks of water pipes to carry water from the source lake or basin into Rome. When the pipes had to span a valley, they built a siphon underground: a vast dip in the land that caused the water to drop so quickly it had enough momentum to make it uphill.
The Romans made concrete by mixing lime and volcanic rock. For underwater structures, lime and volcanic ash were mixed to form mortar, and this mortar and volcanic tuff were packed into wooden forms. The seawater instantly triggered a hot chemical reaction.
Men can lop off nearly 2.5 lbs to account for their clothing while women can only subtract around 2. And this holds true, unfortunately, no matter what the weather outside. So no more making allowances for that thick wool sweater. Now you know exactly how much your clothes weigh.
