So tonight my friend showed us a "cool trick"- after emptying a beer bottle he rubbed it against the cornor of his apartment and we all watched in amazement as it stuck there. He explained that it was friction but I'm wondering if maybe his walls are just the perfect size. I didn't realize that glass & stucco created any kind of friction but I am not an expert in the matter. Can anyone affirm his answer or kindly give your own?
