The lightning rod, which Benjamin Franklin invented in 1749, is a metal pole mounted atop a building that draws lightning’s electrical charge away from the structure.
The rod is attached to an aluminum or copper cable that’s connected to an underground conductive grid. This allows the electricity to dissipate harmlessly.
Because lightning tends to strike the tallest object in the vicinity, lightning rods must be taller than any buildings or other objects in the area.
If installed properly, a lightning rod will carry a lightning bolt’s electrical charge through the path of least resistance along the cable into the ground, reducing the risk of fire or heat damage from the strike.

Alchemy is a short film about transformation. In nature, everything is constantly changing: the earth, the sky, the stars, and all living things. Spring is followed by summer, fall and winter. Water turns into clouds, rain and ice. Over time, rivers are created, canyons carved, and mountains formed. All of these elements, mixed together, create the magic of nature’s alchemy.

The man and his wife were curious about what the stamp was for, so when they got home, the man took out his magnifying glass to try to see what is was. In very small letters, the stamp said, “When you can read this, come back and see me.”
