5. Don’t leave a bottle of water in the car.

If you possess a car, there is a very good chance that you always have a bottle of water in it. Keep in mind that this is a pretty risky practise, particularly in the summer, whether you hold onto the water bottle out of concern for emergencies or simply to increase your water intake. The issue is that because the water in the bottle serves as a lens, it might catch fire if sunlight shines through it, especially if the bottle is placed on a dark surface. Although unlikely, the potential is still there. Take your water bottle with you the next time if you don’t want to be one of the uncommon cases of water causing a fire.
