Try this at home. You will need:
- Large ziplock bag
- Tube of superglue
- Drinking glass
Here’s what to do”
- Place the glass into the bag. Make sure you touch the surface using the pads of your fingers.
- Lay the bag flat on the counter and squeeze a few drops of glue into the bag. Be careful not to get glue on your skin. Do not glue the glass to the bag.
- Seal the bag tight.
Here’s what happens”
The vapours from the superglue will build up in the bag and crystallize on the fingerprints. A day later, you will see starchy white fingerprints on the surface of the glass.
