This is a fun magician game for children to try any day.

You will need:

  • A calculator

How to do the trick:

  1. Ask the adult to hide the screen from everyone and put in their age.
  2. Ask them to multiply the age by 2.
  3. Then add 1 to it.
  4. Multiply the result by 5.
  5. Multiply that number by 10.
  6. Ask the adult to write the answer down in a paper.
  7. Look at the number and ignore the last two digits. The number you are left with is the adult’s age.
