How to make a simple plasma globe

A simple plasma globe would amaze you enough. All you have to do is to find an ordinary electric bulb. Since these bulbs are filled with gases to prevent the filament from corrosion and make it much brighter, you can ionize the gas in the bulb and turn it to a plasma globe.
Not all of the bulbs have the same gas composition so you may have to search for.

This circuit is grounded. You are grounded too and this means there is more availability for current to pass through your body. Take precautions for the high voltage cable and the conductive parts of the bulb so prevent yourself and other ones touching them. When you approach your fingers to the bulb you’ll observe plasma attracting there. As you dare to touch the glass you may find tiny sparkings hitting your finger without pain but they will burn out your tissue. Intense lightning hitting a point in the glass sphere would cause that point to heat. With the tiny coil, haven’t seen this caused the glass to break but it’s possible. If the glass breaks then there will be a chance that sparkings may jump from the bulb’s wires to your fingers. Another danger is ozone, produced by the corona built up at the outer surface of the glass, that is harmful to your lungs. Also ultraviolet emission is very high for your eyes in this operation. So run your globe only for a short period, in a well ventilated place, avoiding to touch the bulb, and at an optimum voltage so it won’t break and hurt you.
