We are going to San Francisco for a few days in May with the highlight being touring Alcatraz. One of the requested souvenirs is the Fog Globe.
I've checked the measurements and I can get it in my carry-on. The problem is I don't know if I will be allowed to carry it on the plane due to the "liquid" inside. Does anyone know if the Fog Globe "appears to contain less than 3.4 oz or 100 ml of liquid (approx tennis ball size)" per security's carry-on rules regarding snow globes?
I was hoping to not check any baggage and only do carry-on's. If I did do "checked" baggage I was afraid it might freeze and be ruined.
