Step 1: Materials Needed
The Materials you will need are a cardboard box, aluminum foil, black paper, tape, cellophane wrap.
Step 2: Cover the Inside of the Box
In order to absorb the heat and the suns rays it is better to cover the inside of the box with black paper since the color will help retain the heat needed to heat up food you plan to cook.
Step 3: Cover the Flaps or the Box With Aluminum Foil.
In order to reflect the suns rays towards the middle of the box where the food will be cooking cover the flaps of the box with aluminum foil.
Step 4: Cover Top of Box With Cellophane Wrap
Covering the top of the box with cellophane wrap will keep all the heat inside alllowing the suns rays to pass, Meanwhile not allowing the heat to escape. In order to retain the most heat tape it down to create a good seal.
Step 5: Optional
You can use the string to keep the flaps at an angle in order to reflect the light rays into the box creating a stronger source of heat into the box. Or you can use tape both work good.
Step 6: How to Use
In order for the solar oven to be efficient use it on a day with no clouds, and lots of sunlight. This will greatly reduce the time it takes to cook things and increase the temperature of the oven. It is also advised to put the oven at a slight angle to capture the suns energy better.
