Tool: Its a bird, its a plane, its a flybar !

Its a plane, its a bird, its a flybar -
the Flybar has changed bouncing up and down forever...the space hopper and skateboard now need a new place to be stacked up.

Ok.. you don't know whats flybar... come on...

Ok.. you don't know whats flybar... come on...!! Of course you know that you can just stand on a stick with peddals and hop up and down feeling like you are flying.. feeling like you are a bunny... feeling like you stand tall among all ... feeling like you have spring in your walk... feeling like you are the jumping superhero !!!

If you want to catch the various variations you can do a flybar, here is a cool video which shows almost 80 variations... gee! you never knew you can jump in so many ways !!

Alright, now lets do a bit of technical tune check by ToonTune on the flybar...the Flybar uses the principle of elasticity to its advantage. In case you have still not studied this principle or are just not recalling it, here is what I recall on elasticity as "the ability of a material to return to its original shape after its shape changes". But here's the catch... while designing anything if you extend beyond its elasticity limit, it can break... yeah, break and yeah, if it breaks you could be in some trouble. But hats off to flybar makers, its resilient and its elastic.

"Springs ... they stretch, they can store energy that can be used to do work in the future. This type of stored energy is elastic potential energy. As elastic potential energy is released, it is converted into kinetic energy, or energy of motion. ... a rider bounces on a pogo stick, his weight and the force from his legs are stored as potential energy in the elastic material, either a spring or an elastic string. When the elastic material recoils, all of the stored energy is transferred back to the rider, who uses the thrust to bounce higher. "
