The Discovery Plasma Orb is equal parts fascinating and educating! Watch as the colorful tendrils of light jump around on their own, then follow your touch or voice, responding to physical contact, speaking, or even music! Place your fingertip on the glass surface and watch the pink and purple strands of light gather around your finger in an amazing combination of science and art! The Discovery Plasma Orb teaches about physics and chemistry! The plasma floating around the orb is a mix of noble gasses and display the visible tendrils of light when the electrode at the center emits alternating electric currents. Placing your hand on the glass creates a discharge path with less resistance than the glass and plasma, hence why the light is drawn to your touch! Mesmerizing interactive light PLASMA LIGHT RESPONDS TO TOUCH AND SOUND : The tendrils of light appear in shades of pink and purple and react to both touch and sound. The built-in sound sensor responds to your voice, music, and other sound effects, so try speaking or playing your favorite songs for an out-of-this-world experience! EDUCATIONAL STEM TOY – LEARN ABOUT GASES AND ELECTRICITY : Learn about noble gases and their interaction with electricity with the educational Discovery Plasma Orb! The Tesla coil in the center emits high voltage alternating electric currents through the plasma, composed of noble gases. This combination produces the exciting colorful effects you can see, because your touch creates a discharge path for the electricity and light to follow.
