Crafting:
Sand Sifter - Iron Sword + Dropper
All recipes are floor crafting

Tutorial:
After placing a Sand Sifter, if you want to actually sift sand, then you will need to place sand above
on top of the Sand Sifter. You can actually do this because of the armor stand hit boxes, so you will need
to make a pillar next to it and place sand on that, and let it fall on top. Sand will take one second to sift,
and after it does the Sand Sifter will destroy the sand and reveal one out of eight random items. These
items include coal, iron ingots, gold ingots, gunpowder, string, golden nuggets, flints and charcoal! If
you want to remove the Sand Sifter, you will need to look for the part of the dropper that you can see
the droppers hit box, and then break it to get it back!
