Finger Prints

A piece of broken glass was found under the table where the ransom note was left…

Is there a fingerprint we can use to identify the suspect?

DO NOT USE SUPERGLUE WITHOUT A PARENT/CARER

You’ll need:

  • 2x piece of foil

  • Superglue

  • Large sandwich bag

  • Gloves

  • Bowl of warm water

  • Evidence A

  • Scissors

What to do

Use the foil to create two containers

Place the small container inside the bigger one.

Wearing gloves remove the glass (Evidence A) from the evidence bag holding it by the edges to avoid any contamination

Place the glass inside the larger foil tray

With help/ supervision from a parent/ carer add 4-5 drops of superglue to the small tray (pull the lid off then snip the end off the end of the tube before adding drops to the tray)

Place the large tray (with the small tray + superglue and glass inside) into the large zip lock bag and seal

Place the whole bag into a bowl of warm water (tap water) and leave for ~30mins

After the 30 mins, carefully remove the glass and check out the fingerprint.

While you wait for the finger prints to develop have a look at some other evidence
