whats a bad idea/product?

What makes an idea or product bad? well how about gum that tastes like beef or chicken? does that sound yummy to anyone? Or how about ketchup that is green? you can eat a hot dog that has green ketchup and maby brown mustard. i think that everyone at ball games would love to eat this! How about a alarm clock that gives you just a little electric shock in the morning to get you going for your busy day? Are you really going to tell me that people dont want to be electrocuted in the morning? Maby people would be interested in buying a shampoo that smells like their pet? if you wanna be close to your animal now you can smell that them! What makes a product or idea bad? would these really be unsellable?
