    Now, take a black paint or black spray and coat the soda bottle completely. Wait for a few minutes until the paint or spray dries well. It helps in preventing the heat from escaping. However, if you do not have paint then you can use a black fabric as well. Make sure to secure the black fabric with a thread or an elastic band so that it collects heat properly.

    Now, place the soda bottle in the sunlight where it can receive the rays of sun. Put it in a closed car because it is a great idea, working effectively. Other than that, you can place it behind glass on a window. You can use a shinny equipment like a mirror or foil to grab extra power and to attract the rays of the sunlight. Leave the bottle in sunlight for a few hours until the water warms properly. Wow! You have enough of warm water without using even a single unit of electricity.
