From Trammell Hudson's Projects
Sometimes when you have an old harddrive you want to be sure that the data is unrecoverable. Time to put on the safety goggles and fire up the kiln to 600C.
We used Settlers of Catan pieces and a sand flask. Poured the melted drive from the crucible into the flask and hoped for the best.
Not fast enough, not enough air return, etc. Oh well. It was a first and only attempt to see how it worked.
We got two cities out of it. Perhaps with more practice we could make a whole set.
