Giant Fingerprint

Fingerprints are very small and hard to explore and investigate. In this fun little science experiment you will use a balloon to expand your fingerprint to gigantic proportions so you can see the arches, whirls, loops and more.

 

Materials:

  • Balloon
  • Ink pad

 

Instructions:

  1. Stretch your balloon several times so it is easy to blowup.
  2. Lay the balloon on the table and flatten an area big enough to fit a fingerprint making sure there are no creases in the balloon. 
  3. Press your finger into the ink. 
  4. Now press your inked finger onto the balloon.
  5. Gently roll your finger to capture your entire fingerprint. 
  6. Blow up the balloon and tie it off.
  7. Enjoy inspecting your Giant Fingerprint.

How it Works:

When the balloon inflates, the image of your fingerprint stretches out and grows. This allows an opportunity to inspect your fingerprint. 

 

Make This A Science Project:

Can you imprint other things on the balloon that enlarge in the same way as the fingerprint? Do other types of paints act in the same way as the ink?
