Many household objects can be used for something entirely different than their main purpose. When disasters strike, emergencies occur, or you just get bored and want to be creative, there are many ways to transform the common item into a life-saving tool. We scoured the web and found the best survival hacks that include: turning a headlamp and a jug of water into a bright light, using dryer lint and petroleum jelly as fire starters, turning glasses into a signaling device, creating an all-natural refrigerator, turning a watch into a compass, converting batteries with tin foil, creating a homemade generator, using a condom to store a gallon of water, how to pick a lock, purifying water with bleach, making an air horn from household items, and using cardboard to create a solar oven.
