Chef and owner Grant Achatz and his team at Alinea Restaurant in Chicago, Illinois have recently been serving edible helium-filled balloons as dessert for their patrons. This video shows a bit of how they make it and how to eat it. It looks like you need to suck out the helium first and then eat the sugar-y balloon remains (which has a dehydrated apple string). Alternately, like the diner in the video, you can sing the Star Spangled Banner while high on the helium.
