Over Here,

it is not uncommon,

 to see someone walking down the street with a bag of of say coca cola or 7up, with a straw in it for drinking, 

 I guessed these tied bags are for take home,

but I was wrong, they are all made of glass! these are actually hollow and solid glass sculptures by Dylan Martinez titled "H20/SiO2." I have to admit they all had me fooled, I really thought they were plastic bags tied and filled with a drink, what a talent, not only as a glass craftsman but as a photographer to make the glass look like water, not an easy thing to do.
