Switch Or Stick Riddle
There are three doors: Door 1, Door 2, and Door 3. Behind one of these doors lies eternal bliss, but behind the others lies eternal despair. You are allowed to choose any door, and you pick Door 1. Suddenly, Door 3 is swung open and revealed to be despair! You are give another choice: you may stick with the door you chose (1) or switch to the other (2). What should you do?
Hint:
The answer may surprise you: switch. Due to something called the Monty Hall Paradox, you will statistically have a better chance of making the "correct" choice. The concept is as follows:
Door 1 Door 2 Door 3
All have an equal chance to be correct:
Door 1: 1/3 Door 2: 1/3 Door 3: 1/3
After choosing Door 1, the remaining two have a 2/3 chance of containing the right choice:
Door1: 1/3 Doors 2 3: 2/3
If Door 3 is removed, the probability does not shift to 50:50. Instead, it is:
Door 1: 1/3 Door 2: 2/3
Thus, you should switch. Did you answer this riddle correctly?
YES NO

Swinging At The Park Riddle
A man and his 6 year old daughter are swinging together at the park. Each is on a separate, identical swing. The man has three times the mass of the child.
Which swings faster? And more importantly, why?
Which swings faster? And more importantly, why?
Hint:
The speed at which a pendulum swings is called the period and given by the equation:
2 x pi x square root of (length of rope from fulcrum to Center of Mass divided by gravity)
Since gravity is constant, the only thing that effects the period is the length of rope. In the above scenario, you assume the man is taller then the child. Therefore his center of mass is higher. This makes the distance between the fulcrum to the center of mass shorter then for the child. The man swings faster. Did you answer this riddle correctly?
