7. Your favorite dry cereal

Good For: Crunchy snack-lovers
Complex Says: If you love dry cereals like Honey Nut Cheerios or Rice Krispies, they're ideal as car snacks that won't leave your hands messy. If you use your hands to put the cereal in your mouth, stick to non-sticky cereals like those. However, if you really love sticky cereals like Corn Pops, use a protein shaker bottle.
