In this video I'm making a Fidget Spinner from empty bullet shells which I bought from a local shooting range in Antwerp (Belgium) The Spinner is also bigger then a normal spinner, but it's not meant to be spinned in one hand, or doing tricks with it. It's more meant as a collectors item. This is just a demonstration on how to make a fidget spinner with molten brass. The holes for the bearings were drilled a tiny bit smaller then the bearings themselfs, so in order to make them fit i had to put them in liquid nitrogen to shrink them. Once they warmed up again they locked themself in to place.
com: You're not going to get a lot of requests for this, but I thought it'd be kind of interesting to see. Cast Sierpinski's Gasket or Koch's Snowflake in aluminium or copper to create a large fractal antenna. Most fractal antennas are very small and used in cellphones. Just curious what a larger one connected to a coaxial cable might be able to accomplish.
