The 8-inch Plasma Ball is an incredibly beautiful lighting device. Originally invented by Nikola Tesla, the first plasma lamp was an “inert gas discharge tube", designed to study high voltage phenomena. This home version is a delight to play with, as the plasma bolts react to you, converging towards your touch, or pulsating to sounds. The plasma globe provides mesmerising atmospheric lighting that also improves air quality by generating negative ions. It's a great gift for young scientist, making an inspiring piece of decoration that also functions as a low-light lamp. The lamp also excels at party lighting, delivering a funky science aesthetic that reacts to the music.
