cooking with the sun

For inquiry we were making an oven only out of a box tin foil and black paper we first had a big box then we had a cutter to cut it out we first did cut the card board and cut it out  into a squire and put tin foil on the top of the card board and clue it on then we got piece of black paper and put in on the bottom but we didn’t clue it on we taped it on then we got plastic and put it under the foil. Have you made a solar oven before?
