By now, most of you know what you can and can’t bring through TSA airport security checkpoints. This includes no bottles of water, no knives, no explosives, and of course no other liquids more than three ounces.

But you might be surprised by what the TSA does allow. A waffle iron?  Who would want to do that? Well some people do, and the TSA says yes.  A sewing machine? TSA says yes. A frozen bottle of water? Yes.

What about a foam toy sword? That’s a no because it might be mistaken for a weapon.

And here’s a surprise. Can you bring handcuffs in your carry-on bag? Yes, but here’s one piece of advice. Don’t forget the keys.
