Ah, the differences in should and could... i say, NO! You should not. You CAN, and you COULD, but should not anyways

Such a nice presentation. Even though I learnt all of these things in high school but somehow never pictured the mechanism so clearly until I watched it here.

Bravo.

Yep, nothing new here but great for the kids to learn this stuff in a fun manner that they are more likely to remember.

We had an electrician in my high school who used to do this to entertain the students. He was touching the high voltage cables while standing on a thick rubber insulation (as in 4-5 cm thick) Years after i finished high school i heard he had died doing that trick. Apparently something went horribly wrong and his body made contact with the ground.
No idea what was the voltage of the box he was always fiddling with but it was the main one that the whole school was getting electricity from so i guess.. a lot..

#4 Well, nothing teaches you about electricity better than seeing a man getting fried in front of your eyes... X_X

Cool teacher....I was lucky to have one like him when I was at school...( back in the dark ages). he was probably the most popular teacher we had.

for those who know the subject instead of just memorizing the book...
