So we all know what happens to a milk that you buy in a regular shop. Sooner or later it goes bad. some milks go bad much much later. And as we all know you cant make curdled milk out of milk you bought in shop. And this is what happened to me when I had my milk for too long - it started glowing :) ok, ok thats not exactly the case here, I was just enjoying playing with led lamps inside milk bottles. So here you go - trees with milk lights. And the first version of my lamp set up can be found here: https://www.360cities.net/image/milky-dark-light
