I found this thing laying on by the sidewalk, outside my house. it just caught my attention cause it was shiny so i took it home... and of course i decided to shine my laser through it and to my surprise, it acted as one of those liquid sky things! here are some pics, i also found out that it doesnt only refract, but also reflects so it created a 360 degree liquid sky. pretty cool cause it was free! lol . just thought id share my luck
