This is just a fun project with younger kids and is not really a high duty cooker. Enjoy it and have fun with it. Other things that might cook are an egg and possibly cookie dough (small cookies).

Jeffrey - Good suggestion! I know there are improvements to the design, this is something put together to show my grandkids some basic solar operations. Don't know if I succeeded, but they did like the smores!

Wondering if it might get hotter if everything were painted black and some kind of reflector (aluminum foil) was placed on the open cardboard flap.

The paper is not directly exposed to sunlight so it does serve as a bit of insulation for the foil pan. Please remember, all this really does is just present some simple ideas to a child. The overall design, like you implied, could be tweaked to make it more efficient. Basically, it is just a s'mores warmer.

Does the newspaper really help? I would imagine that the foil would reflect the light better without the newspaper.

The lid can work as a reflector when covered with foil. Love your idea.
