An attractive but repulsive spin-up method

Cool way to boost a hand-twirled finger top to a state of high-speed sleep...

Art is how we decorate space, music is how we decorate time ... and with spinning tops, we decorate both.

Everything in the world is strange and marvelous to well-open eyes.

The working principle is not very different to the Top Secret top, except that the coil is on the side instead of below and pushes and pulls (from the description on another video), while the coil in the Top Secret only pushes away. I prefer the old version, as it used just one transistor while this one uses a whole Arduino!

The Top Secret was the second top in my collection, after the Levitron. My first throw top (a Monarch) was only my forth top.
