I'm going to show you (as best as I can) how to make light transmitting concrete. Google it, and you will be amazed at how beautiful it is! I was desperate to get my hands on some...but considering the cost, I decided to make some with stuff I already had around.
This material has the strange effect of looking shiny or sparkly...but it's dull concrete at the same time! It's very entertaining to show off or play around with.

Step 1: Making the Mount
Step 2: Making the Mold
The whole point of this is to make a mold to cast the concrete into.
Step 3: Fiberoptics
Cut a bunch of small 1 inch segments by breaking off about 10 wires from the bundle, and cutting them short en masse.
Step 4: Placing the Fibers
I used pliers. If you use them,too, be mindful not to crush the fibers...they are quite fragile, even though they are plastic.
Step 5: Pouring the Concrete
Mix the concrete pretty thin...you do not want air bubbles.
