Today was the first football Sunday of the year. Hundreds of thousands of people across the country were out tailgating, which means lots of spare beer cans. What you see as an empty beer can, can easily be turned into increasing your wi-fi signal.

Also, I should add, make sure you do this once the effects of the beer have worn off, because you are working with sharp objects.
