right around 400 seconds he uses a ball to cinch the sink

great idea and a good use for those old tennis balls


nice sinks but seem more like an oddity and might only look good in just
the right house


keeping it clean and glossy might be impossible and the finish would need
to be impervious to all the things that bathroom sinks encounter from
toothpastes to lotions and cosmetics and daily wear and tear

would like to see it after a couple of years use
