USB Plasma Ball (with 4-Port Hub)
$23.00
A plasma ball is a vacuumed glass ball with inert gasses inside. An alternating current, at relatively high voltages, are pumped into the sphere via an electrode in the center. This energy causes electrons to be stripped from the gasses. The arcs will congregate to and follow your touch while your finger touching the glass. It can expand a USB port into 4 which means it is combination of fun and usefulness. Of course, you can also turn off the light if you are tired of it.

プラズマボールは真空にしたガラス玉で、内部には低圧の惰性ガスが充填されています。
中央の金属球に通電すると、内部のガスが高圧により火花を発し、無数の絶えず揺れ動く光線が発生します。
手を徐々に近づけると光線の手に近づき、不思議な視覚が現れます。
