Dusted!

Learners press their fingertip onto a clean Plexiglas sheet. The fingerprints are then revealed as learners dust over the print with fingerprint powder. They can lift their prints with clear tape, and press the tape to black paper to have a record of their prints to take home. This activity is part of Crime Scene Chemistry in OMSI's Chemistry Lab.
