The latter ionizes the local air and the radiation pressure evacuates the resulting plasma, forming a spherical plasma bubble that stably traps the radiation. In short, plasma is a partially ionized gas and therefore the ability of the negative charges to move about makes it very responsive to electromagnetic fields. Additional Questions. Thanks for contributing an answer to Physics Stack Exchange! If you touch it long enough, you get filled with electrons and can light up a light bulb! Click the card to flip . This is possible because the plasma inside the ball and the conductor outside it act as plates of a capacitor, with the glass in between as a dielectric. Although this behavior itself is mostly harmless, you'll want to take steps to ensure that your turtle doesn't actually catch your finger, as some turtles do bite. Creating an enhanced path to earth by touching the globe increases the strength of the discharge, which is why the arcs are attracted to your hand if you touch the globe.
