#### You Will Need

• Sponge ball and cube magic set
• Audience

## Steps

1. Step 1

#### Show the audience the ball

Show the audience the red sponge ball in your hand and tell them you will make it disappear.

2. Step 2

#### Squeeze the ball in your fist

Squeeze the ball through a small opening in the top of your closed fist, passing it from one closed fist to the other, palms inward, so that it is always concealed from your audience.

3. Step 3

#### Turn the ball inside out

Turn the ball inside out while passing it from hand to hand. The red ball is a trick ball that, when inverted, becomes a large square with a hole that conceals a black ball.

4. Ask them to guess which hand the red ball is in. Whichever they choose, they’ll be surprised when no red ball is in either hand.

5. Step 4

#### Reveal

Reveal the large red square that was the red ball and a black ball when you open your hands.

6. In math, a magic square contains rows, columns, and diagonals of numbers that all add up to the same number.
