Today, I filled it up with a quart of mineral oil and turned it on, but nothing happened, I could hear the pump running so I removed the top cover and turned it on again,...after about a minute I could see the oil rising in the clear plastic tube...it took a good 1 1/2 minutes before the oil reached the end of the tube and started filliing the trough on top, and another minute before it worked itself around the entire top and then started dripping down the strings....But I had a problem...The first 2 or 3 strings were running almost at a steady stream and the other strings stood dry... To slow the stream I knotted about an inch of fishing line and dropped it into the first holes...instantly the flow backed up and the oil started traveling to the other strings...For the light I used a flicker bulb. I like the way the flickering light dances through the moving oil drops.

It looks cool in my dark bar, but capturing a photo of the oil drops is really difficult
