I honestly didn't think that it would work. Yesterday the temperature was 38° C and we took a magnifying glass out into the sun to burn some ants. I focussed the light onto some old dry leaves and they just burst into flames. That was really surprising! If you're going to do this at home make sure you have a clear area and do it under supervision. We found the ants a little too difficult to focus on because they ran away.

Interesting for bugs but, I hope no one will use it on people. Gil
They ran away??? Why is that ;-)
