When I occasionally get the hiccups, I take a big, deep breath and hold it in. Then I keep taking "sips" of air, continuing to hold my breath as long as I can, thus compressing the diaphragm. It works. I had my boyfriend try it when he had the hiccups a few weeks ago, and it worked for him, too.
Spoon rings have been around since the dawn of spoons. There was nothing special or proprietary about what that dude was doing. Selling cheaply produced (he ain't handmaking all those rings) rings at a premium isn't new, and I feel sorry for the people duped by him.
