There are some genius designers and stylists walking around Anthropologie. I always hated science but I fell in love with this decor before from a wedding featured on Style Me Pretty. While I don't have some extra cash lying around to buy these cylinders at Anthropologie, flea markets or yard sales are fine alternatives. A cool science looking living room without all the not-to-pleasant chemical smells!
P.S.: I just remember that fiance was in a Chemistry specialty class in High school. Yes, we had those classes in Vietnam, thank you very much.
