Kitchen Cabinet CSI

Did you know you can dust for finger prints using common cooking ingredients?

To dust for fingerprints, sprinkle talcum powder or cornstarch on dark surfaces and cocoa powder on light surfaces (like the outside of a drinking glass) where there are visible prints. You can use a small paint or makeup brush with very soft bristles to gently swipe off the excess powder and leave the print. Use clear tape, sticky side down, to lift the print and then stick it to an opposite-colored paper. What kinds of patterns do you see?

If you've got superglue lying around, you can get really fancy and lift prints using fuming.

This strikes me a as fun-for-all-ages experiment to try, not to mention an important life hack. You never when these detective skills could come in handy.
