This is one of the more interesting things I have done lately, and I thought is would be way more difficult to get good results. Casting metal really opened up a whole new level of diffrent things that can be done, and removes the barrier to when you want some special little thing that you cannot seem to find anywhere. So make it! I casted in aluminum, which has one of the lowest melting points of  all metals. Watch the video and see what you think!
