    Without using a glove (or anything such as a bag in lieu of a glove) nor holding any intrument or tool, how can one pick up with one's hand a non-magnetic coin at the bottom of 30 cm of water in a bucket, and without the hand getting wet?
    Hint: think of something to protect your hand other than anything made of plastic or rubber or resembling a glove in any way.
    It can be done!
