Today the boys made a solar oven from a pizza box (instructions to build your own: http://www.solarnow.org/pizzabx.htm) It was a lot of fun, and pretty impresive! The internal temperature got up to 160 degrees before the sky became overcast. Unfortunately, our oven wasn't a success. After 2 hours the biscuts hadn't baked much at all and a sudden gust of wind blew our ovens off the picnic table. Still, it was a fun science lesson for the kids!

While the boys were busily gathering time and temperature data, I took the opportunity to sew some more. I found a great vintage fabric and made another wrap dress:
