Solar S'mores

The sun is out and we are ready to enjoy a favorite summer snack.  Using poster board, cardboard, aluminum foil, glue, string, and clips, we created Copenhagen Solar Cookers for s'more science fun.  Once in the sun, the ovens heated up to 150'F in a matter of minutes and were able to melt the chocolate on our marshmallow fluff covered graham crackers.

Here is a video on how to build your own - How To Make Cogenhagen Solar Cooker.  We even made mini ones using 7"x7" poster board squares and 4"x4" cardboard center!
