- 3 bags of M&Ms
Have 3 young ladies come to the front of the class.
Give the first girl an unopened bag of M&M's.
Give the 2nd girl a bag of M&M's that have already been opened.
Give the 3rd girl a bag of M&M's poured directly into her hand.
Ask the girls which of the 3 would be the most tempted to eat the M&M's?
