Of course not all snow globes are permitted. That would be bananas:
Some Snow Globes are Permitted Now: TSA now allows small snow globes in carry-on luggage when packed in a passenger's plastic 3-1-1 bag. Snow globes that appear to contain less than 3.4 ounces (approximately tennis-ball size) will be permitted if the entire snow globe, including the base, is able to fit in the same one clear, plastic, quart-sized, re-sealable bag as a passenger’s other liquids.
The post also has bullet points on what kinds of food and deodorant are permittedfull lists here and here respectivelyand a reminder to "double check your bag for guns." Apparently handguns and rifles are still banned on domestic and international flights. So that's your update on rules: small snow globes now yes, firearms still no.
But while we're on the topic of things not to bring to airports: in addition to leaving handguns at home, TSA would also prefer that travelers resist the urge to show up wearing watches that look like tiny bombs. Someone tried that a little bit before Thanksgiving and things went exactly how you'd expect.
