Solar s’mores…


Why make a solar oven you ask? Let me tell you my logic behind our afternoon craft. We just needed something to do this afternoon. Yup, that’s it, the kids were bored. For those of you who don’t know us, my husband and I are both teachers, so we have been home with the kids for two months now…we are looking for stuff to do! (Mom, skip the next sentence…) Yesterday I taught the kids how to burn leaves and paper with a magnifying glass. They loved it! The kids wanted to know if they could try burning a marshmallow, so that’s how the idea of the solar oven came up. (ok mom, you can read now) so, we dug up a cardboard box, black tape, tinfoil, and a box cutter.

I cut a hole in the top of the box. In retrospect, it might have been better to cut the hole out of the side, because it was wider, but we cut our window in the top.

Then we made a window out of Saran wrap and taped it down with the black tape.

Next we lined the inside with tinfoil. I used the glue stick to stick it down around the edges.

Then i figured adding a black stripe on the bottom would help attract the sunlight…maybe I should actually google how to do this…

At this point I realized we didn’t have any graham crackers, but it was too late to turn back, so i dug out some arrow root cookies

The kids added a few marshmallows and chocolate chips to each cookie

Then we found the sunniest spot in the yard. I put a black cloth around it to try to attract some more heat


While we were waiting, we had a tea party…

Then after about 35 minutes, we opened up the oven (by this time, it was three o’clock. I think this might have worked better if we had tried at at twelve o’clock.)

The chocolate melted pretty well, but the marshmallows just didn’t heat up enough to be gooey. But, I didn’t hear any complaints…


Since we already went to the trouble of making the solar oven, I might try again on another hot sunny day, this time at noon… Maybe we could try grilled cheese sandwiches!
