Build a Gravity-Powered Water Raising Device in 5min
AS water is poured into a sealed container so long as the air can't escape (use a valve) then water should be forced through any other exit point (all under pressure inherent to the system ie, not altered by external forces other than the addition of water). a tube and raised container to...- tonyjames

Build a Gravity-Powered Water Raising Device in 5min
Also any rubber like vessel with the air squeezed out will only draw water in/up due to the force of the atmospheric pressure pushing down on the surface of the water (same principle as a drinking straw). atmospheric pressure supports a coloumn of water 10m high at sea level, some thingsto think...- tonyjames

What Causes the Rocks to Slide on Death Valley's Racetrack Playa?
Some interesting comments , i'd like to add to the idea that heat plays a roll and maybe gravity even though the rocks can appear to move slightly up an incline. If the rocks are storing up heat during the day time and the ground is cooling rapidly at night (due to surface area) maybe it is...- tonyjames
