Incredibly powerful hand gyroscope - in glowing Blue!!!

Okay, for you people out there who are fans of the Powerball Gyroscope (and we know you are out there) here is a new toy for you - the Powerball in glowing Blue. All the fun and joy of the original, but with an oh-so-super-cool blue glowing LED built inside. The blue LED light starts to glow once the Powerball begins rotating and will glow ever brighter as the rpms are increased. Looks like something from a Tron movie and is especially fascinating in a darkened room. Trust us, you will be mesmerized by this little gem.

The Powerball is started out at about 2,500 rpm and is slowly worked up to speeds over 13,000 rpm. It's a lot of fun to see just how fast the Powerball can rotate. There is a digital display built into the Powerball that can display the realtime rotor rpm as well as store the highest achieved rpm - a high score which will remain in the memory until you achieve a higher score or clear the memory. Use it around the office to see who can achieve and maintain the highest rpm speed. You will never get tired with your repeated attempts to continuously get higher and higher rpm speeds. It's a lot of fun and dangerously addictive.

In addition to being a fun and intriguing gadget, the Powerball also is a great way to directly experience the Gyroscopic Effect (you know - angular momentum, linear momentum, centripetal force, precession and all those neat physics properties). It's a compact little display of Newtonian physics at it's best.

The Powerball Gyroscope has these features:

• Perfectly balanced and capable of rotations up to an incredible 15,000 rpm
• Built-in blue LED light - glows brighter as gyro rotates faster
• A fun and practical demonstration of physics properties (centripetal force, etc.)
• High-quality materials and construction
• Great strengthening tool
• Can provide gentle rehab for carpal tunnel, RSI, arthritis, tendonitis
• Unique digital counter that displays rpm and/or highest speed
• Does not require batteries
