Reusable, Disposable Mixing Cup

Good kitchen measuring cups don’t belong in the shop, or any place where you might feel tempted to use them for mixing epoxy, two-part finishes, or other nasty chemicals. If you can convince the cook of the house to let you borrow the good measurer just once, you can make a decent shop-grade substitute from a plastic cup.

Using water, carefully pour set amounts, then mark the side of the cup with a permanent pen. Instead of repeating that measuring and marking process with each mix, simply slide a second cup inside first. If can keep the master cup clean, you can mix a boat’s worth of epoxy without needing to redo your measurements.

In addition to preserving domestic harmony, my disposable measuring cup prevents the accidental contamination that can occur when mixing chemically reactive ingredients in the same container.
