Botijo
A botijo or búcaro in Spanish, is a traditional Spanish porous clay container designed to contain water. The botijo has the property that once filled and placed in the sun, it cools the water that it contains, acting as an evaporative cooler.
The botijo has a wide belly and one or more mouths where it is filled and one or more outputs called pitón o pitorro to drink from. The botijo is a typical element of Spanish culture and may vary in shape, color and material.
Operation
The operating principle of the botijo is as follows: the stored water is filtered through the pores of the clay and in contact with the outside dry environment (characteristic of Mediterranean climate), it evaporates, producing a cooling (2.219 kilojoules per gram of evaporated water). The key for cooling it, is by the evaporation of bleed water, as the water evaporates, it extracts thermal energy from the water stored inside the jug (and from the environment itself too).

Petty Wage
by: Swingin' UttersI've said and once too often, some things I'd never say again. in streams of thoughts unbroken I fish for a few good men
Sundays and holidays and twelve hours straight no pay for bloody hands and believe me they pay a petty wage
my poor self pity speaks with sobbing, mumbled words strewn with the awful taste of bad, cowardly prose
I'd take some time to get my posture set straight if I had the chance I'd break and subdue the scheming hands of fate.
Wrap up your limp red mass of knuckles and fingertips it's fighting time and time to battle with your wits, time to spit back when you're spit upon, when you're left for head. time to hit the road when the road you're on had run out of tricks
