The Glass Necklace
Well, for some value of 'actually work'.
Title text: Well, for some value of 'actually work'.


The heat from a lightning strike can fuse sand into glass. When this occurs in nature hollow tubes called fulgurites are formed. Cueball uses this knowledge and a spark of handiness and ingenuity to create an entirely home made glass necklace for Megan. Here is some inspiration to do it yourself.


[A man is drawing a diagram of a cylinder with electrical terminals on either end]
[The man is shown at a workbench making the device in a workshop]
[He kneels down on a beach and scoops up sand]
[He pours the sand into the cylinder]
[He ties a spool of string to one end of the cylinder, and ties a deflated weather balloon to the other end]
[The weather balloon is inflated, and raised up into the clouds as thunder rumbles]
[The end of the string is tied to a stake in the ground, and lightning is flashing in the background]:[Lightning hits the balloon, travels through the cylinder, and fuses it's contents]
[The man follows the string to find the cylinder]
[He detaches it, opens it, removes a solidified piece, and admires the piece]
[He takes the stone to a jeweler]
[The jeweler examines, grinds, and sets the now-shining stone in a necklace]
[The man approves of the final result]
[He gives it to a woman]
