The plasma lamp contains a gaseous mixture, the base can be produces high frequency electromagnetic waves that cause the gases to turn into lightning, which is an ionized gas.
The ions produced emit some energy in the visible region and appear as colored"streamers".
The plasma lamp responds to your touch.
The lightning is attracted to your hand as it nears and touches the glass ball.
You may feel a slight tingling sensation, which is caused by the vibrations on the glass ball as the electrons strike the surface of the ball.
