I made this solar oven from nothing but:
a shoebox (with lid attached, not removavel),
an old winter shirt,
a plastic bag,
some black paper,
two pencils,
and alluminium foil.

Step 1: the lid

Cut the lid like the image.
<p>thanx i made it for my brother he got to make project on solar energy i m very very thankful to u thanx once again </p>
<p>Um... How do you put stuff in it? Do you have to rip off the plastic bag?</p>
<p>No. You just open the lid as you would normally do on any shoebox.</p>
well, does it cook anything, or is this theoretical! Show us something tangible.
I put an apple on it around 12 o' clock, in a cloudy day and at 20 o'clock it was almost cooked, but solar ovens, unless hi-tech they are very slow. To show you that solar ovens work, the first was able to melt rock!
Rock ?
yes, basalt!
