In this instructable, I will show you how to tell if a dollar bill is real or fake, using household materials.
Step 1: You will Need...
You will need:
A dollar bill
Step 2: Folding
Fold the left side of the dollar bill about 1/4 the way in. Unfold to a 130 degree angle.
Step 3: The Magnets
Slowly bring the magnets close to the 1 in the top left corner.
If the dollar bill moves toward the magnets, the bill is real.
Step 4: How does it work?
The dollar bill has magnetic ink which is attracted to the magnets. This is done to prevent counterfeit bills.
