Question

What is the material used to build a water cooler?

Answer 1

A water cooler or water dispenser is a devicethat cools and dispenses water. They are generally broken up in two categories: bottleless and bottled water coolers. Bottleless water coolers are connected to a water supply, while bottled water coolers require delivery (or self-pick-up) of water in large bottles from vendors.

Water cooler may also refer to a primitive device for keeping water cool.[1]
