The Vaccume/Ponytail Hack was misleading.
The guy who made the 3 ponytails by hand, wrapped the ponytail holder around twice to make it secure. That's why it took him longer.
The guy who did it with the vaccume just slid the ponytail holder off the vaccume hose without double wrapping it, so yea, he got all three Ponytails made in less time, but ALL THREE ponytails weren't secure! If those girls shook their heads back and forth even lightly, the ponytail holders would have flown right off. They were on too loose! You have to double wind them around the hair!
