Radiator

What is stronger than a swordsman and more efficient than a fascist bureaucrat? Take a guess. No, you’re wrong. Do you give up? Here, I’ll give you one last hint: This thing is used to heat or cool. Sorry, you’re wrong again — the answer is: a radiator.

You can find radiators on buses or in homes. However, if you do end up gaining access to an old black-&-white apartment and locate its radiator, please refrain from draping a large cloth over the item, as this could start a fire.

Typical radiators are made of metal. Touch them with your bare hand, if you wish to feel discomfort from extreme temperatures. Have you ever seen water boiling in a pot? Did you know that heat is given off by steam? 

Imagine an engine under the hood of an automobile. A cooling system is needed to prevent its crankshaft from being damaged by the ultra-high temps. That’s why, when trekking across the desert, I always wear this water jacket. Look at the network of tiny tubes: they keep the situation cool and under control. Most good engines contain a pump with turbine-like impellers in front which drive a pulley via chains that connect to a vortex up through Hell.
