I have to say, this little project was cool even for the adult in the room! All you need is a sunny day and dark construction page to make magic happen.
Arrange several items on a sheet of construction paper, preferably with interesting silhouettes. Travis helped me select a key, button, block, and CD case.
Now leave the paper out in the sun for at least a few hours. When you’re ready, remove the items and voila! The sun will have faded the paper, leaving darker shadows wherever your items were on top.
A neat little way to show the power of the sun…
