A serious design flaw in the dual-propellor caps and beanies may lead to horrific injury. The two propellors should have opposite thread, so that they rotate in opposite directions with total angular momementum 0. Instead, they rotate in the same direction, doubling the angular momentum.

Imagine the extreme torque-induced precession when the unsuspecting geek tilts his or her head during rapid propellor rotation. Not a pretty thought.

I'm sure that Geek Culture will issue a safety recall immediately, and provide opposite-threaded propellors. Learn a lesson from GMC, guys.

I'd better stick my neck out and give this a good spin, so I don't end up like Mary Barra...

There is NO pattern of incompetence and neglect in our propeller beanie laboratories, or on our sales showrooms around the country. Unfortunately, in our Universe, seemingly benign actions may lead to devastating consequences. Those geeks with pencil-thin necks wearing double propeller beanies in high rotation situations may experience angular momentum sensations. Consider it an opportunity to work out the neck muscles, including the sternocleidomastoid and the trapezius, to build a strong, thick, manly neck like an NFL lineman!

FYI, we do offer, for customers who ask, the option for opposite-threaded propellers in double propeller beanies.

Those who order triple propellers... well, they are on their own. May whatever gods they believe in, have mercy on their neck muscles!!! [Big Grin]

Snaggy, do not develop a windmill beanie! While during acceleration there is not too much reaction. While decelerating the blade will regress very forcefully especially if the generator is loading the blade.

I hope that Nitro took that Pic as she may not have enough neck strength to take the full forces of regression.

There is another problem with these devices should an unaware person walk or put an extremity into the prop arc severe damages may result.
