USB Plasma Ball

Just the word plasma makes you think of going boldly where no-one has gone before. However, the beauty of this awesome USB Plasma Ball is that you don't have to wrestle Klingons in the outer regions of the Thark Quadrant to play with it; just plug this neat gizmo into your USB port, and streams of red and blue plasma light will flicker out from the core of the hand-blown glass sphere throwing mesmerising light trails across its surface. Touch the sphere with your fingers, and blue light will shoot out towards your fingertips.
