1) I want one of these adult sized. Dangle books above my head, put me on slow rock. I'm good.
2) I want one of these too. Think of the energy I'd save at work. I can roll around and spontaneously sit if I feel like it. I can also bounce exuberantly without injuring others. Put some easily digestibles on the tray in front of me for constant snack time. It's a win-win.
3) Admit it. You kind of think that eating off of rubber covered utensils would be awesome. No more teeth clacking, no more enamel getting knocked off with that one-second-too-soon bite down. And you get that satisfying give every time you bite a little too hard. Go ahead, don't be ashamed to want it.
