Here's an amazing trick that lets birthday guests try their hands at a little forensic science by lifting their own fingerprints.
What you'll need
- Pocket mirror
- Soft pencil
- Sandpaper
- Tape
- White paper
How to make it
Individually, have each kid press his or her fingertip on a pocket mirror.
Cover the entire print with graphite dust by rubbing a soft pencil with sandpaper. Blow gently to remove excess dust.
Carefully stick a strip of tape to the print and slowly peel it off.
Stick the tape to a piece of white paper, and the print should be distinct.
