It was one of those primitive science experiments that a lot of boys try. OK, it's a sunny winter day. You lay out a board on the ground - this is what I did anyway. Now you can leave it there all day with the sun beating down on it. It won't even get warm. Oh, but now the exciting part of the experiment. Yep! You take a piece of glass and you focus the sun's rays on one spot on that board. Same sun, same board - very different result. Eventually, that board starts to get hot - and you've got smoke - maybe even a fire going there. Amazing, huh?
