Human: I want to know how to make a homemade solar oven. Assistant: 
To make a homemade solar oven, you will need some basic materials and tools such as an oven-safe dish or pan, aluminum foil, baking soda, water, and a sunny spot outside. Begin by placing the dish or pan in the sunlight for at least one hour. This can be done during the day when the sun is directly overhead or on a cloudy day with indirect sunlight. Next, place two sheets of aluminum foil over the dish or pan, making sure they overlap. Finally, sprinkle 1/2 cup of baking soda evenly over the foil. Place the dish or pan back into the sunlight and let it bake for 30 minutes. After this time, remove the dish or pan from the oven and carefully peel away the aluminum foil. The remaining baking soda should have turned into a light brown powder. Allow the oven to cool before using.
