Japanese Electric Flyswatter-Zapper

Why does it stop zapping after they die? Are they not conducting anymore?

[u/SuperUranus → u/meta-radar]

It’s operated by a human.

It zaps the dead flys too when activated.

No, you could not select target with static setup like this. Current flows only where there is least amount if resistance.

The reason the electric arc is not continuous is that the fly does not itself form a permanent short circuit. It temporarily provides a conductive path through the air.

When the fly dies, its body quickly dries out and becomes charred. This changes its electrical properties, so it no longer provides a sufficiently conductive path to sustain the arc. Once the current stops, the ionized plasma channel in the air collapses almost immediately.

A living fly, on the other hand, contains a lot of water and is relatively conductive. When a new fly approaches the electrode, it distorts and concentrates the electric field enough to trigger a new discharge.

So the device doesn't necessarily detect whether the fly is alive or dead. The dead fly simply no longer meets the electrical conditions required to initiate or sustain the arc.

Why do flies gather there?

[u/PamonhaSelvagem → u/logosfabula]

The first one might just be a coïncidence.
But the other are simply atending each other’s funeral. They are flies, but they are not that rude.

[u/logosfabula → u/PamonhaSelvagem]

It’s a double, triple, quadruple tap then!

[u/enerthoughts → u/logosfabula]

Ignore the wrong answer, he pasted a lure on the inner pole to pull them in, also these flies are kept in confinement for ease of filming.

[u/Bilbo_Einstein → u/logosfabula]

Check the pillar the orb is upon, it’s got black and white stripes to attract flies. Works on a lot of agricultural-scale flytraps the same way

[u/BluetheNerd → u/Keisari_P]

The dead flies still get zapped, the reason it’s not continuous is someone is choosing when to turn it on or off. It has a conductive grounded ring surrounding it, even without any flies there if it was on it would be continuously arcing to that ring, the flies, both dead and alive, provide an easier path to that ring which is why they get zapped.

[u/SuperUranus → u/Keisari_P]

I didn’t say it selects a target. In fact, I said the complete opposite of that.

It’s operated by a human and zaps both dead and alive flys when activated. As you can clearly see in the video.

[u/Junethemuse → u/Keisari_P]

Lmao what are you on about? They didn’t say anything about targeting. They said someone is controlling when it fires and noted how it zaps everything without distinction: aka, not targeted.

You are did use a lot of words to show you didn’t quite read what they said.

[u/dont_worry_about_it8 → u/Keisari_P]

Sounds smart but no. Idk why you said no then proceeded to say you can’t select a target. No one said you could? He literally just said a person is turning it on or off. Soooo actually most of this comment irrelevant as hell.

[u/iKnowRobbie → u/Keisari_P]

Only the carbon they result in IS conductive, this is inherantly false. You're misunderstanding 40,000 volts on a critical level. Corona, surface effects, capacitance are things that occur at high-frequency high-voltage energy impulses. These effects would continue to cause polarization reactions in their bodies, literally pushing and pulling them from each other. Dessication does mitigate the potential, but not greatly enough to negate the stream of electrons that a tesla coil pushes. It WILL find the least resistant path to ground. These are laws, goddamnit.
