You can sift the mix just about anywhere! But be mindful of your surroundings.

Choose a location that is stable and will not be damaged by water, dirt, or the specimens.

Plumbing + sand don’t mix!

The sifters are 10 inches wide, so you’ll want a container that is at least 15 inches long and 11 inches wide. Your container should be large enough to comfortably fit the sifter, with some room to move.

A typical 16-quart plastic storage bin works perfectly!

Since you can’t sift the mix in your bathtub or sink, you’ll need a container that is at least 6 inches deep.
