the "Julia Child" of kids' hands-on science
A sense of balance is also extremely important because sometimes instruments alone are not enough to keep a helicopter oriented properly in the air. Pilots may have to make very subtle corrections. So here’s a test for balance. Be forewarned. Not many people can do this, maybe one in twenty.
1. Stand at attention.
2. Make two fists and extend your arms straight down by your sides. Point your index fingers to the ground.
3. Close your eyes.
4. Bend one leg back at the knee so that your lower leg is parallel to the floor and you are standing on one foot. Don’t let your foot droop. You must maintain your knee at a right angle.
5. Keep your eyes closed and hold this position for ninety seconds.
6. Try not to shake.
I learned about this from a Scotsman who told me about this test to qualify for the British Royal Air Force. He couldn't pass it, nor could I. In fact, no one I knew could rise to the helicopter pilot challenge except a Navy pilot in my family. He held the position perfectly for two minutes. Solid like a rock. No problem.
It’s clear that when it comes to certain skills not everyone is equal. Some people are not even close. So very few people are in the running to become helicopter pilots. You're probably not one of them but this may change with training.

On Monday, we will begin a whole week of postings that celebrate different aspects of the Halloween holiday -- some history, some science, some literature, some hands-on activity, and even something kind of ghoulish about holiday itself.
We'll start with a little history. Kids wear costumes, and you even see tiny babies or silly little dogs in costumes, but a jet? You'll find out how that happened from Amy Nathan first thing next week.
