Hey /sci/, I heard lightning can strike sand and create glass out of it and I was wondering what you guys think the radius of a lightning bolt striking sand is? Also how deep would it go into the sand?

"Glass" is a general term, the silicates fused during the strike are stony in appearance like a chunk of cement even though they're technically glass.

The fused lightning trails can go about four meters or so deep in the sand. Typically the fused sand is about 10 cm across, more or less.

I don't know how big around the lightning bolts are. Even if I got close to one I don't think I am quick enough to measure it.
