Heavy Cotton T-Shirt
What do you get if you mix Barium, Cobalt and nitrogen? Some type of alkaline metal I assume. I'm only working off high school level chemistry and don't really remember but, if you put together the symbols for Barium, Cobalt and Nitrogen, you of course get BaCoN. If you love bacon and you love corny jokes that really only make sense if you look at it than this T-Shirt is perfect for you. BaCoN is delicious, the food not the chemical compounds that specific to making this joke. But, bacon is really good and you do not need a Bunsen burner to make it.
