Products That Scream, ‘Wow, That’s Smart!’

There are some products that just make you go, “Wow, that’s smart! I wish I’d thought of that.”

Maybe they solve a common problem, maybe they were invented by a kid.

What’s the secret to coming up with a product like this?

Amilya Antonetti from Lucky Napkin, a company that helps entrepreneurs take their product from concept to consumer , says the formula is simple: “The product concept has to be something that somebody wants to repeat — whether it’s a slogan, a logo or a product,” she said. “If people are repeating it, there’s a way to make money,” Antonetti said.

Here are 10 of those products that make you go, “Wow, that’s smart!” and want to tell someone about it. They were invented by engineers, moms — even kids. And some of them made a ton of money from that one simple idea!
