A few days ago, on one of the rare days that I actually blow-dry my hair, I got a stroke of inspiration: we could make our own wind tower. We dug a cardboard box and Styrofoam packing insert out of the recycle bin and got to work.
I traced the shape of my blow-dryer nozzle on the top of the box and then cut it out. Then I stuck the nozzle into the resulting hole, and propped the blow-dryer up on the packing insert. I used masking tape to hold down the "cool blast" button and we were good to go.
That all took about 5 minutes. Here's what it looked like on the inside:
Notice that the air intake thingie on my blow-dryer is kind of pointy, so it doesn't rest flat on the Styrofoam. We would have had to figure out something else if my blow-dryer was flat there.
Here's a view from the top:
Ping pong balls and coffee filters both flew really well. We didn't try cupcake liners today, but I'm sure they'd do great too.
We had fun taking pictures of the kids being "wizards" and making their balls float in mid-air.
We ended up getting an entire morning of entertainment for the cost of 5 minutes of work and a raid on the recycle bin. I love it when that happens!
Here's a video of the contraption in action:
