21. Coal as an Odor Defender
A bad stench in the car can ruin your drive and mood too. It can also cause carsickness, which can leave you in a worse state than you were initially. A few pieces of coal in the car can absorb the bad odor, leaving the air smelling fresh and clean. You can have them on board throughout the drive or leave them overnight in the car. They are an ideal option for people who are sensitive or react to scented air fresheners.
