Fly repellent - I had to repin this again for you to see. YES IT WORKS! Oh my, it looks hokie but our temps have been upper 90's and no flies in my back yard have been spotted. I spoke with a women who grew up on a dairy farm and she swears by it. She said they used 5 pennies. Go figure.
You've been closing snack packaging wrong your whole life unless you've been doing it like this the whole time--in which case why haven't you told us before!? Yoinked from http://j.mp/zdx3ll so as not to crash the site and/or make you look at nekkid people.
