ice lens?

I walk to the bus stop in the morning with my daughter, and I'm reminded
ever since I was a kid, I can't resist stepping on that weird kind of
extremely thin ice that forms a bridge over a puddle....but I can't figure
out how it forms- maybe it forms and water underneath slips away or
sublimates.

Is it really possible to get any clarity with an ice lens? (we're months
from April 1..)

Maybe a lens to collect solar energy to light a fire or a cigarettski.
