Here at SFG we love sharing life hacks, especially ones that could prove useful in the future. This informative video lists seven tricks that could save your life in a pinch, and all of them use objects that you probably have in your home. Who knew that a soda can, aluminum foil, and and empty egg carton had this much potential? While we hope that you never actually have to use these in a life-or-death situation, they're good to know, just in case.
