So if 3 and one half tubes were full it would be 3:30 am/pm There's a pump at the bottom feeding water though a small drip valve which drips into each tube, the computer at the base tells a motorized track to move to the right at each hour. At the end of 12 hours the unit drains at the bottom and starts over again. It took the longest amount of time to build this one of the two projects. This one was made from plexiglass and we had to use "plexi-weld" glue on which melts the pieces into one....really neat. Anyways that doesn't really work to keep an air tight seal all the time as it bubbled as it dried so we had to put some epoxy at the base of each clear tube to keep the water in. 5 days of figuring out how to stop the leaks, about 3 days just putting it all together. The window placed 1st place, the clock, second. This was a stressful month but its all done now and these projects look neat.
