Editing Bottle Blaster (section)

== Demonstration ==


# Fill the bottle most of the way with water, leaving a small amount of air space at the top. Let the audience know that you are going to be breaking off the bottom of the bottle ''without touching the bottom''. Feel free to ham it up (claim that you are using the force, magic, etc.) or to claim your rubber mallet has special powers.
# Place out the tub or similar underneath you and the bottle. Hold the bottle in front of you, with your non-dominant hand gripping it around the neck, and the mouth of the bottle fully visible. Be sure the bottle is held low, around waist height. 
# If using your hand, strike the mouth of the bottle with your dominant hand, striking it downward with the palm of your hand. Be sure to cover the entire mouth of the bottle when you do so, and to allow the bottle to slide in your non-dominant hand. It may take a few attempts, But when you hit it correctly the bottom of the bottle will fly off, spilling water everywhere!
## If using the rubber mallet, be sure to strike the mouth of the bottle evenly with the mallet head, fully covering the mouth of the bottle. When done correctly, the bottom of the bottle will fly off, spilling water everywhere!
# Ask the audience for ideas on why this happened. Do you really have special powers? What is the secret to this demonstration?
