Eliza... take a couple of pieces of metal rod (copper wire works best) and bend them such that one leg will cross your palm and be about one inch longer than your hand is wide. The other leg should be about a foot or more. Make a "fist" with your thumb pads against the nails of the index and middle fingers such that the rods may move freely in the inch or so diameter "hole". Point the rods straight ahead. Walk over running water. Try this on a bridge at first... a wooden bridge if possible.
