Fun with a ceiling fan and balloons

We just got our first ceiling fan installed in the “jam room” downstairs. This reminded me of something I discovered a few years ago. Watch this footage from a Halloween/birthday party at a friend’s house in 2005:

A funny thing happens when you turn on a ceiling fan around some helium-filled balloons (in this case, birthday balloons). The fan blades knock the balloons to the side at high speed. Then, they’re gently pulled back in by the air that’s flowing in to replace the air being pushed down by the fan blades. (In other words, the low-pressure area above the downward-blowing fan blades.) Physics in action!

  • Interesting demonstration Luke, I think the same thing happens on a larger scale to create storms here in Texas. :-D
    Btw I noticed I didn’t have the book “Get Started with Jammables” I don’t want to be missing anything, should I get it? Thanks in advance.

  • Ah, so *you* must be the “Toni from Houston, TX” on our testimonials page! I figured it was you, but I wasn’t 100% sure.

    Which edition do you have? If second, then the only big thing you’re missing out on are the 100 songs in big print; and you might as well get Big Print Songs for the same price and get double the songs.

    If your edition is the First Edition (or there’s nothing in the top-right corner of the front page), the answer’s a little trickier. Email us.
