When I was about 8 or so, my two younger siblings and I thought putting things into the front of an old fan was funny. We were latch-key kids. We had lots of time on our hands. My poor single dad.
The fan was old and therefore very well made and very heavy. Things like hot dogs, carrots, Barbies, and a ping-pong ball were fed into this fan. The ping-pong ball was the thing that finally killed the fan by breaking off a blade, but before that happened my brother found the most ultimate fan 'friendly' item on the planet. Baby powder. It's a wonder my dad didn't sell us off to the first taker after finding the whole house covered in the fine powder that was shaken into the front of the fan blowing on high.
This is my karma for having laughed and encouraged my brother (until I couldn't breathe):
It snows indoors with crushed popcorn peanuts!
