In the Air Launch Siphon, a stream of liquid separates into droplets inside of a sealed air filled chamber, preventing the liquid going down from having contact with the liquid going up (see illustration below). I'm having a difficult time finding references for this type of siphon. This siphon appears to be relatively unknown, for some odd reason! Here's a short video of the Air Launch Siphon (https://upload.wikimedia.org/wikipedia/commons/4/4b/AirLaunchSiphon.ogv) in operation.

Can you put a paddle wheel in the box and make it spin?
