alternatives to concrete? for project similar to DIY Light transmitting concrete Answered
I recently came across this instructable Search for " DIY light transmitting concrete" and I was wondering how I could make something similar but in the shape of a ball, or a light bulb, So I can have a LED inside it and have it shine and spin freely.
Perhaps filling a tennis ball and drilling holes for light?
Im ind of stumped on this one. any ideas???
