no,unless you consider a glass beer bottle edible. eating silicon dioxide in any form, other than as sand or small, rounded drops would be suicidal.
Lightening+Sand = Fulgurite
Nothing unfortunately
Fulgurite
fulgurite
To measure the abundances of rare earth elements in clinopyroxene and olivine of iron-silicon in a fulgurite, were made to determine the oxygen fugacity required.
When a bolt of lightning strikes loose sand, the electric charge vaporizes a thin hole and melts the zone around it, creating an instant froth of natural glass. These tubes-fulgurites-can be a meter long or more, but they're fragile, and what you see in rock shops is usually a piece like this, 4 centimeters long and as light as pumice. Sometimes a fulgurite forms in solid rock. This fulgurite specimen came from the Sahara Desert in Morocco. Fulgurite is scientific Latin for "lightning stone."
fulgarite (sometimes spelled fulgurite)
It turns into a rock called fulgurite (fused quartz). When sand is struck by lightning, the silica in the sand melts and fuses, forming a glass tube called fulgurite. Fulgurite is generally rare, but can be found all over the world. The fulgurite can be a variety of different colors depending on the mineral content of the sand. (see related link)
lightning makes glass when it hits sandy soil. its called a fulgurite.
You could get a fulgurite. But you'd probably just get damaged concrete.
If lightning strikes a sand bed, it will form a fused tube in the sand, known as Fulgurite. This form is not confined to surface conditions, tubes are found up to 15m below the surface, and Fulgurite tubes may be up to a few cm in dia.
The energy of a lightning bolt striking in sand can heat the sand and fuse it into simple glass. The glass forms as tubes called fulgurites (thunderbolt rock) and the material is called lechatelierite.
