What we are trying to accomplish by putting jars or sponges or dishcloths in the microwave is to super-pasteurize them. The boiling water temperature in the microwave kills most of the bacteria that would compete with and overgrow the yogurt bacteria (or make your dishwashing cloth stinky and possibly hazardous). That is the difference. For most immediate uses, you don't need to kill all the bacteria, but for long term storage (like canning) that IS what you want to accomplish.

If you place your black box in the sun on a hot summer day, it can heat to over 150 degrees depending how large your openings are. paint the OUTSIDE of the box black.

Almost a video in what not to do, but Eric is completely at ease and unruffled when things go wrong, which is actually a great lesson for kids - if at first you don't succeed, try again. Thanks for making the cardboard box solar oven construction look so easy. I have a solar oven and love to take it camping. Makes the very best rice!

What other safe alternative do we have?

Yep, I use my solar oven a few times a week. Out here in Tucson, Arizona, we have plenty of sun to play with. Never made yogurt though. Humm . . . I think I'll do that. My solar oven gets hotter than yours, but it cost more than a cardboard box; so there's the trade off. :) Thanks for the tips. Fun video, dogs and all. Yep, I use my solar oven a few times a week.
