r352-73c) 2-1/4" Fulgurite lightning strike and similar items

(Internal # R352-73c) This is a fulgurite from West Texas, average 2-1/4" long, with hole. This piece has a visible hole where the lightning went through. Nice one of a kind display piece. Last photo is an illustration of an extraordinarily large fulgurite found in Libya as an example of how large fulgurites can get. What's a "Fulgurite"? This large specimen you see above from the Libyan Desert shows what happens when LIGHTNING strikes SAND !! "Fulgurite" means "lightning" in Latin, folks. Each flash of lightning releases an average energy of 1 billion Joules. Air temp may reach 10,000 - 30,000 degrees K., with currents from 10-100KA for microseconds. It vaporizes sand and rock to make amorphous glass. Tubular fulgurites may reach over 8 meters, but are fragile. What an interesting thing to add to your rock mineral collection! We make them very affordable, though smaller...most still have a hole where the lightning went through. Click on our Store tag for SIMILAR items. We ship WORLDWIDE, check shipping chart for rates!
