"Lightning is the most common cause of building fires, especially in rural areas. Andrew Larsen, executive director of the Lightning Protection Institute, Arlington Heights, Illinois. "Scores of lives and billions of dollars in property could be saved each year if buildings were properly protected against lightning," according to C. When lightning strikes, the bolt of extreme heat melts the sand and instantaneously forms a twisted, branching piece of clear, shining glass.The extensive network of lightning rods, cables and clamps needed to properly protect a commercial building or factory against lightning. He attracts lightning by using lightning rods stuck into the sand. How does a lightning rod attract lightning? Immediately get out of and away from ponds, lakes, and other bodies of water., and more items. Never use a cliff or rocky overhang for shelter. Immediately get off elevated areas such as hills, mountain ridges, or peaks. This begs the question “What should you do when lightning strikes?” Sometimes, people refer to this as heat lightning because it most often occurs in the summer, but it is no different from regular lighting. If you see lightning but don’t hear thunder, it is because the thunder is too far away. What happens when there is lightning but no Thunder? The tumbler is forming sand from a process called “selective abrasion”. Turn on the tumbler for as many days or weeks as necessary to form “sand” (please follow “best-use” practices for your tumbler!). Purchase a rock tumbler and add some of your glass ( coarsely crushed ), water, and some abrasive. You might’ve seen this phenomenon depicted in the 2002 Reese Witherspoon romcom Sweet Home Alabama, or maybe in a viral photo that circulated the internet in 2013.įulgurite: When lightning strikes sand, magic is formed., and and geologyin., and com/2014/06/amazing-fulgurites., and html., and and britannica., and com/science/fulgurite. When lightning strikes a sandy beach, something amazing happens: it creates glass sculptures. These pieces of art are Mother Nature’s coolest tricks. The blast of a billion Joules radiates through the ground making fulgurite - hollow, glass-lined tubes with a sandy outside. When it hits a sandy beach high in silica or quartz and the temperature goes beyond 1800 degrees Celsius, the lighting can fuse the sand into silica glass. Since the lightning vanishes immediately, the water around the sand quickly quenches the mass and preserves what was essentialy the path of lightning through the ground, moments ago. When the sand is struck by lightning, it heats up so much that it melts in an instant around the plasma stream. What really happens when lightning strikes sand? The glass formed by lightning striking sand is called a fulgurite, and it looks very different from the glass sculptures in “Sweet Home Alabama.”. Part of the reason for this is because lightning is unpredictable, and part is because it is extremely dangerous to go near a beach or other unsheltered place during a lightning storm. When lightning strikes, the bolt of extreme heat melts the sand and instantaneously forms a twisted, branching piece of clear, shining glass.Īnother question we ran across in our research was “Why don’t they use lightning to break glass on the beach?”. I a character in the movie “Sweet Home Alabama,” uses the lightning at a beach to transform sand into intricate and delicate glass sculptures. So, can lightning rods in sand make glass? Hot enough that it can melt and fuse sand, silica, and some soils! Petrified Lightning or “Fulgurite” is exactly that, Glass made by lighting! Fulgurite left behind by lightning is a veiny, organic looking artifact made of sand that’s been superheated and then quickly cooled. When a lightning bolt hits the ground, it’s hotter than the sun. You may be asking “Why does sand turn to glass when struck by lightning?” While it is true that lightning can and does melt sand to form glass sculptures that resemble tree branches, the movie’s portrayal of how this happens is not accurate. When lightning strikes, the bolt of extreme heat melts the sand and instantaneously forms a twisted, branching piece of clear, shining glass. But, lightning also follows a path of generally less resistance (it’s not a perfect “path of least resistance” thing). Well, lightning definitely carries enough energy to turn sand into glass. So, can Lightning really change sand into glass? These glass tubes, fulgurite, can remain protected under the ground for hundreds of years., and more items. The glass that results looks like hollow, branched tubes that are covered with sand. When the lightning hits the sand, it tunnels into the ground, making a shape like the roots of a tree. Lightning turns sand into glass under certain circumstances.
