    If you are an Indian using the Word 'India' attached to something that is watched globally, be careful and fully aware of it's Use. Do NOT use that Word casually to generate a Forced Joke.Whatever we speak stays permanently on the Social Media. So use Words carefully. I am an Indian, having already completed my Masters in Computer Science. Now I am chasing Masters in Physics and nowhere had I an Experience where the Teachers were over-Cautious and hyper-panicked. Speak for yourselves and stick to your own personal Experience. Do not generalize it to a complete Nation.

There are zero moving parts, the sound it makes is when the electricity arcs across the spark gap preventing the user from making direct contact with the AC source it is plugged into.

    The other end of the Crookes should have been grounded for best effect. He is relying on the leakage of the current through the wood stand and into the air. That is why the green beam is not that sharp and also has a vertical line where the glass standoff is in the middle - the electrons are leaking down the glass standoff and into wood stand. BTW - safety tip, keep that Tesla coil away from those gas jets.

    Saliha Salam If the pressure is high( due to larger number of gas molecules) we’d have to apply a high voltage. But if a few molecules of gas are to be escaped pressure will be low and we’d have to apply a relatively less amount of voltage in order to observe the phenomena... (by lowering the pressure means the number of gas molecules present are lower and thus for less molecules less amount of voltage will be enough)
