Question

Electronics

I watched the video: https://www.youtube.com/watch?v=P5za9sa4-qk
and I want to repeat this experiment, but it seems a bit dangerous to me, right?

Answer 1

In the worst case, a little spark will click you.
There are only three flat batteries, so the current will be negligible.
True xs what will happen if you have a pacemaker - it’s generally better not to bring anything magnetic or electric to them.
It is much more dangerous to collect it, because you can burn yourself with a soldering iron.

Answer 2

If just like in the video, to feed on three tablets, then no.
