Ever notice how bags of chips or popcorn or cheese curls resemble puffy balloons and weigh almost nothing? Why not take that concept a step or two further? Fill bags with helium for a truly “light” snack. Better yet, figure out how to make snacks that float in mid-air. Maybe whip helium into the mix to trap the lighter-than-air gas in cheesy bubble chambers. Pop a few Hee-Lee-Yums in your mouth and you’d temporarily lose weight … until you started high-talking like a Munchkin. OK, it’s a pie in the sky idea. But I thought I’d float it out there anyway.
