What fun we all had making our own solar oven, here are some photos of the whole process.
|Our instructions were clearly set out on this display board...|
|Selecting two boxes to make our oven. |
There had to be about a 5cm gap between the boxes.
|The gap between the boxes was filled with scrunched up newspaper.|
|We painted the inside of the smaller box black.|
|We made a reflector out of on old corflute real estate sign covered in |
aluminium foil and added a glass lid.
|We did not get to test the oven yesterday as it was cold and overcast all day..|
but it was sunny today so we put it to the test in the sun today.
|In just over half an hour our cardboard box oven reached 100oC - |
so you may even be able to boil your water in it.
