Editing Magic Spoon (section)

===Short Explanation===
The ''Magic Spoon'' isn't actually magical. Instead, the presenter is showing ''Torque'' or a rotational force, and using the spoon as a distraction. To think of torque, think of how a door works. If you push on a door next to the doorknob, the door will open easily. But, if you push on a door near the hinges, it is really hard to open! This is because the amount of force you need is affected by how far you are from the hinges; the further you get from the hinges, the easier the door is to open. 

In this demo, the presenter is pushing on the volunteer's arm to make it move. The volunteer's shoulder is where their arm rotates, so think of it being similar to a door hinge. When the presenter pushes on the volunteer's forearm, it is far from their shoulder and easy to push down! Likewise, when they push on their upper arm, it is really close to the shoulder and much harder to push down!
