How to Fuck With Your Students 101
STEP 1: Buy 3 small, differently-colored bouncy balls
STEP 2: On the first day, bounce only one ball during class so they get used to the color.
STEP 3: On day 2, begin by bouncing the same ball as before. Halfway through class, discretely switch it with a different ball that’s similarly colored (like switching from bright red to orange). Now students are wondering if their eyes are playing tricks on them.
STEP 4: Spend Day 3 bouncing the same color ball as you did on Day 1. Now students are going nuts trying to figure out what’s going on.
STEP 5: The coup-de-grace. On Day 4, carry around all three balls in one hand, and cycle through as you bounce them. (An easy method is to drop a ball from the bottom, use your thumb to push the other two down, then catch the one you bounced on the top. Then repeat.) Now, from the kids’ perspective, the ball is changing colors each time you bounce it. Red, blue, yellow, red, blue, yellow. Let mass chaos ensue as they accuse you of witchcraft and then slowly realize that there were multiple balls.
