Twirly Helicopter Thingy

Anything that flies is a huge hit with my son.  I remembered making these for the kids in my class and looked up the pattern online.  You can find a print out by clicking HERE. I printed out the pattern and folded as directed.  When it was assembled, I handed it over to T and let him figure out how to make it twirl.  It took him a few tries but he soon discovered the best solution was to stand on a chair to get the optimum twirling from it.  He is still playing with this days later. I couldn't get a good action shot but when you drop the "helicopter" it spins all the way down.  Pretty fun.
