Things you don’t do: A cowfence has not a high voltage but lots of Ampère!
And thus an electric bash of the cowfence still can hurt you. In Physics we
have learned, that our body can be powered with thousands of volts
without any harm… as long as we’re not grounded.

These five people wanted to test if one, who’s grounded, will get the electro-bash. The result in advance: Not only!

But watch for yourself:

FRRRRZT! At least, they all earned a good grade for the synchronity!
