It’s sound activated and creates the same fun looks as the larger versions. FUN FOR KIDS: Creates an amazing light show – from every angle! A little bit of science, a little bit of art and a whole lot of cool! This plasma ball is simply the ultimate interactive light show.
It’s fun to see how far you can take your hand away from it as it responds to your energy. The glass is thin and delicate, so be careful around children and pets. I’ll definitely be going big again for gifts and holidays! The ONLY complaint is it doesn’t respond in audio mode.
If you touch something metallic (e.g. the edge of a table) while touching the plasma ball, you may receive a shock. It’s not dangerous, but it can be frightening. Keeping your hand in one spot on the ball for a long time will generate heat.
Put your hand on the plasma ball while it’s on, then turn the ball off. Immediately place your hand back on the plasma ball and you will see electrical bolts flash towards your hand. Take your hand away and clap several times.
The plasma ball is a small Tesla coil. Inside the glass sphere there is a partial vacuum. This just means that some of the air has been extracted. Because there isn’t as much air there, it’s easier to create electrical sparks that are visible.
If you touch a plasma ball with one hand and touch another person with the other, you will give the other person an electric shock. This is because your body becomes an electrical conductor.
If you bring conductive materials or electronic equipment near a plasma ball, the glass may become hot. The high-voltage, radio-frequency energy coupled to it from within the sphere, even through a protective glass enclosure, can cause a mild electric shock to the person touching it.
Plasma balls actually produce small amounts of ozone when touched. This is because the high voltage inside the globe has a very high frequency and this can propel electrons through the glass with high kinetic energy to create ozone-generating micro-discharges at the push of a button.
Can you leave a plasma ball on for a long time? For most plasma globes, this isn’t a problem and you should be able to leave them on for as long as you like. This is usually the case with plasma balls as they don’t run the risk of catching fire as you might expect.
These fronds of plasma make their way from the center of the globe to the edge to reach Earth. Creating an improved path to Earth by touching the globe increases the strength of the discharge, which is why the arcs are attracted to your hand when you touch the globe.
The plasma ball is a miniature Tesla coil. Inside the ball is a coil of wires through which electrons vibrate at a very high frequency. This shakes the atoms around the wires so much that their electrons start falling off! There is a partial vacuum inside the glass sphere.
The very high voltages of the plasma sphere can easily polarize a coin (or piece of aluminum foil) placed on the plasma sphere. By getting your finger just a few millimeters above the dime, you can get a spark out of the tip of the coin.
They are filled with helium & Neon to a pressure less than 0.1 atmospheres, so it would implode and the gases would do no harm.
