Good burning lense
Reviewed By:
Burford (Cherry Hill, NJ)
This lens is thin and flexible. I cut a 5 inch circle from the center and glued it into the rim cut from a plastic Folgers can. It's a powerful burning lens with a a 2 ft focal length. Now to add the Folgers lid to case to protect it.

melt rock
Reviewed By:
Tim Ebert (Auburndale, Florida)
Over twenty years ago my dad bought one of these lenses for me from Edmond Scientific. We made a solar furnace. It could melt some pumice, and burn lots of stuff. I tried using several at once to increase the power, but that task was beyond my skill at the time. The sun moves and changes the focal point. I enjoyed using the lens, but it requires more experience/help than the typical 12 year old possesses to make a real furnace.
