This surprising stunt
makes it look and sound as if you are bouncing a roll off the floor and back up into the air.
You'll have a ball performing it. Sit down at a table across from your kid. Take a bite of a roll,
mumble a comment like, "This is so chewy, it tastes like rubber," then thrust your arm down as if
you are throwing it to the floor.
When your hand is below table level and hidden from your child's
view, toss the roll right back up into the air. Keep your elbow straight and toss with your wrist
only. If you keep the tossing motion out of view, and stomp your foot to make a bouncing sound, it
will look unbelievably believable.
