Extreme Science: Cut and restore a dollar bill

Posted: Updated:
What you will need:
  1. At least two (2) one dollar bills
  2. Rubber cement
  3. Baby powder or cornstarch
  4. Scissors
  5. Unsuspecting volunteer that is about to be amazed by you and your magical abilities!
  6. Adult supervision

Procedure:

1) Prepare the dollar bills ahead of time by spreading a thin layer of rubber cement over the front of the bill making sure to cover the entire center area of the bill. Let this dry completely (which only takes a few minutes)

2) Once the glue is dry, sprinkle the glued area with either baby powder or cornstarch. Make sure that all of the glue is covered with the powder and wipe or blow off the excess powder so that it cannot be seen.

3) I like to draw a line on the back side of each dollar bill right down the middle (vertically) to make sure that they cut it exactly in the middle.

4) Place the bills in your pocket or wallet. I like to have several bills prepared so that the volunteer can pick two bills of their choice, which gives them the impression that it is completely random and by their choice.

Now you are ready for your “volunteer”

5) Remove the bills and have your volunteer choose two bills of their choice.

6) I like to ask them to look them over to make sure that they are “regular” dollar bills. If you do this, it is better to use cornstarch as it will not smell like the baby powder does.

7) Once they choose two bills, put the rest on the table or back in your pocket.

8) Take their two bills and place them face to face making sure that the edges are all lined up.

9) Give your volunteer a nice sharp pair of scissors and ask them to cut the dollar bills in half right down the middle. This is where the line comes in handy (from step 3).

10) Firmly hold the dollar bills out flat holding the ends allowing them to cut the two dollar bills in half.

11) Once they have completed this cut, ask them if they felt it actually cut the bills in half. They will confirm that they did cut them as instructed.

12) Tell them that through the power of magic, you will now restore these bills to their original, uncut condition.

13) Holding the bills in each hand, slowly “open” or “unfold” them revealing your healing powers!

What is going on?

Rubber cement has very unique qualities. This glue is intended to be spread onto both surfaces that are intended to be bonded together. You must wait until the glue is dry in order for the bond to occur. If we did not cover the dried layer of glue with the cornstarch or baby powder, the two bills would have instantly stuck together over the entire area that was covered with glue. Although the powder keeps the glue from coming in contact, once the scissors cut through the layer of glue, the glue is then “pulled” from one dollar bill to the other adjacent dollar bill and, since it is rubber cement, it will stick to itself causing the two separate halves to stick together giving the appearance that the dollar bills have been restored to their original condition. After further investigation, you will notice that the right half of one of the bills is now “stuck” to the left half of the other dollar bill. Make sure that if you choose to tape the dollar bills back together that you tape the correct halves together. Otherwise, you will end up with two bills that each contain two different serial numbers which may cause problems!!! Also, the line that was drawn on the backside of the bill is to ensure that the volunteer cuts right down the center of the bill so that George Washington doesn't end up having 3 eyes on one bill and only one eye on the other as this would take away from the affect that you are trying to achieve.
