Just this summer we introduced the girls to the power of the magnifying glass, burning a small hole into wood and smelling the smoke. (Of course, parental supervision needed.)

This activity takes a bit of patience, but the result is a pretty cool display of harnessing the sun's magnificent power.

You'll need a magnifying glass and a piece of wood...and a sunny day.

Find the right distance of the magnifying glass from the wood where the sun's light is concentrated into a pinpoint of bright light.  Slowly, slowly, slowly start to burn the wood with the concentrated light.  Move the pinpoint of light down and around to draw a picture or write the first letter of your child's name.

It's a pretty cool memento to display-"harnessed sunlight".
