Flying can be scary, but it’s actually quite safe. However, there are some questionable items that one is allowed to bring on board the airplane. Check out what you can bring on an airplane or what is prohibited on an airplane. But for some funny reason, you’re allowed to bring the following 10 surprising items on an airplane.

Dry Ice (Under 4.4 lbs.)

Not sure why you’d need to bring dry ice aboard a plane, but just in case you do, I would recommend you first know how to properly handle dry ice. Being that it can be a dangerous substance, it’s in fact remarkable that you can just bring it as a carry on as long as it is under 4.4 lbs.

Screwdrivers (Under 7″)

Being allowed to bring a screwdriver is not only shocking, but also scary; however, indeed if the screwdriver in question is under 7″ or 17.78 cm, then you are allowed to bring it on board. It makes sense if you’re into construction and repair, but for us common folk, it’s best to leave them screwdrivers at home, even if it is allowed.
