possible improvements



Use four layers of tinfoil.

Use two layers of clear oven bag for window.

Do the project in a room where no doors, windows, or the fridge are being opened.  (This can let in cold air and affect the temperature readings)

Use four boxes instead of two.  Thjere would be more layers to keep the heat in.  Also there would be more air pockets to stop the heat from escaping.

Angle the walls of the interior solar oven towards the center/steel plate so that they reflect the heat more directly onto the food.

Use a magnifying glass instead of the clear oven bag to cover the window.
