    My dad and I decided to build this solar cooker. It look promising, but we only managed to get it up to 100 degrees before clouds covered the sun. Can't wait to try it again on a sunnier day!

    Today my amazing coworkers and I teamed up to make our own DIY solar cookers! We had a blast putting them together, and I am super excited to test mine out!

    I made a much lazier version of this project :) mine is just a foil lined box covered in clear plastic. For better results, next time I'll paint it black. I successfully toasted English muffins!

    It's getting toasty in LA this summer! What a perfect opportunity to harness the power of the sun with your own DIY solar cooker, am I right? Putting this together proved to be a task in hilarity, team building, and some downright GOOD fun.

    Taking a break for lunch, a friend and I decided to build this solar cooker. We didn't get around to painting it but we're looking forward to putting it to work!

    Nothing like a nice, hot Summer Los Angeles day to inspire some solar cooking! All this being said, I gathered some of my favorite folks to take inspiration from the Nest Solar Cooker Do and build some of these ourselves. It was so fun to get together and bond over a great cause and we can't wait to test out the cookers!
