Water Into Fire?
« on: November 09, 2026, 12:02:35 AM »
I watched a YouTube video.  Apparently, a clear plastic bottle of water can be used to filter sunlight into a beam of heat for ignition of a flame.

Has anyone ever tried this?

Careful with plastic water bottles getting hot in the sun…..and then drinking them later.

You can do it with anything that will focus the sun’s rays onto a single spot.
