- snow globes, regardless of size or amount of liquid inside, even with documentation
- chlorine for pools and spas
- nunchakus
- cattle prods
- bows and arrows
- meat cleavers
But don't worry, you can still take the following necessary items:
- personal lubricants of any size (must be declared if over 3 oz)
- toy transformer robots
- cheese in pressurized containers (less than 3 oz)
- bone marrow, blood products, transplant organs (must be declared if over 3 oz)
- prosthetic breasts (must be declared if over 3 oz)
And don't try to slip any of those fold-over sandwich bags. You have to have a functioning zip-top bag. No exceptions.
