Not yo' Mama's box fan

We have one of these super duty box fans that swivel up - fancy - it moves the 90 degree plus air in our sun room around and cools Samuel on the top bunk at night.  It's been a great fan.  Today the fan provided multiple minutes of entertainment.  1. turn on fan  2. add balloons from birthday party two weeks ago 3. ahhhhhhhhhhhhhh!!!!!
