That's how much distilled water is contained in just one bottle for our dispenser. We have it delivered, because we can't drink or cook with the tap water in Beijing. So our 18.9 liter bottle sits jauntily astride the dispenser in the kitchen, just waiting for a thirsty person to happen by.
But sometimes, no one is thirsty. Like yesterday. I wasn't in the kitchen. I was in the living room, watching the boys play with the airplanes Uncle Sean sent (thanks Sean - those things rock!). Bart wasn't in the kitchen - he was in the office, placing an internet order. Kyra wasn't in the kitchen. She was running between the airplanes and the office.
Ainsley was is the kitchen. Ainsley, whose favorite Chinese expression is "xi shou," which means "wash hands." Ainsley, who realized yesterday that you can certainly "xi shou" quite nicely with water direct from the dispenser. In fact, if no one is looking, you can just open the spout and wash those hands sparkling clean - with all 18.9 liters of water.
I'm not terribly good at gallon to liter conversions. So I can't tell you exactly how many gallons our dispenser holds. But I can tell you that 18.9 liters is enough to make a mighty fine pond in the kitchen.
