The radio-frequency energy from the transformer is transmitted into the gas within the globe through an electrode at its center. If a hand is placed close to the globe it produces a faint smell of ozone, as the gas is produced by high voltage interaction with atmospheric oxygen.
The gases inside are not dangerous. The voltages can give you a bit of a shock even through the unbroken glass but it's very low current so not dangerous either. And of course the broken glass will be sharp. So try not to cut yourself, and dispose of the wreckage appropriately.
A plasma ball is a high-voltage electrical device and should be used with caution. The frequencies it emits may interfere with cell phones, Wi-Fi and cordless phones. Because the plasma ball emits electromagnetic radiation, it can interfere with pacemakers.
Plasma is rich in nutrients and salts. These are important in keeping the body alert and functioning properly. Losing some of these substances through plasma donation can lead to an electrolyte imbalance. This can result in dizziness, fainting, and lightheadedness.
Now all this plasma globe and etc the temperature is room temp only. The electron gets high temperature up to 20000 degree K, but there only 1 or 2% of total gas is ionized.
At the globe surface as well as the electronics. There is a chance that in warmer days the electronics can get burned off. If you leave it on for days, it will most probably die anyways. But again, these equipment work at extremely low powers, and as long as you don't open them up, they are pretty safe to use.
If you touch the plasma ball, all of the electrons will go through you to the ground. You see only one big spark inside the ball where you put your hand. If you touch it long enough, you get filled with electrons and can light up a light bulb!
Small novelty plasma balls need only a few thousand volts at a low safe amperage for operation. But larger, thick-walled globes used in museum displays often can take up to 30,000 V for generating quality streamers. Despite this high voltage, the spheres are safe to the touch because the glass acts as a dielectric.
At that high temperature the lightning column is a plasma, a gas with many of its atoms broken into electrically-charged particles, both negatively-charged electrons and positively-charged ions. Lightning arises from electrical charges residing on soft hail and ice crystals that move about in the air.
Turn on the plasma ball. Bring the fluorescent bulb close to the plasma ball. As you near the plasma, the bulb will light up. If you are using a long fluorescent stick, you can control how much of the bulb is lit using your hand.
The graceful purple arcs of plasma dancing in a plasma ball are created by a large alternating voltage at its centre, and that alternating voltage creates an electromagnetic field with which we can light a fluorescent tube.
