Review on Ultrathin Magnifier Experiment Concentrator Education by Mike Goodwin

It's 2 pieces of plastic, almost flat! He doesn't even darken the paper so as not to light a fire. Save your $34! UPDATE: The company emailed me and advised me to try it in the sun. I TRYED THIS SUNLIGHT! They charge $34.90 for 2 pieces of plastic that scratch very easily and don't work at all. All the good reviews on this product are fake, I guarantee you!
