Many things that resemble food—because of their crusty coating, sweet odor, or candy-like consumptiveness—are actually just common household objects, poisonous seed pods, or new friends. What are some things you may wish to eat but shouldn't?
Bath Beads: Though they're designed to look and smell like Gushers® Cherry Red Gelcaps with Liquid Extreme Rush Fluid, they have none of the delicious side effects. Bath beads are extremely foul-tasting, and should only be dissolved into a fragrant human soup to be used externally.
Buttons: Colorful handfuls of things are always food, right? Not necessarily. Your grandmother's unmarked mason jars may contain a variety of food to nonfood objects, from hundred-year-old gumdrops (technically food) to needles and other sewing implements (technically not food). Don't be fooled by her pincushion, either—it may look just like a tomato, but it actually tastes slightly worse.
Scented Candles: Legally speaking, there is no imperative against eating scented candles if no one is looking. That being said, someone will always be looking, so a scented candle that creates the illusion of melting lavender petals or fresh-baked cinnamon will make you the most popular person on your block!
