Can You Bring a Snow Globe on a Plane?

Snow globes are one of the most commonly confiscated items at airport security checkpoints — not because they are dangerous, but because travelers consistently forget that they contain liquid. The TSA has specifically flagged snow globes in its official FAQ, and officers pull them out of bags every day. Here is everything you need to know before packing one.

Why Snow Globes Are Treated as Liquids

A snow globe is a sealed glass or plastic sphere filled with liquid — typically a mixture of water and glycerin or, in older globes, water and antifreeze. The liquid creates the swirling snow effect when shaken. From a security standpoint, that liquid makes a snow globe subject to the same rules as a bottle of shampoo or a jar of peanut butter.

The TSA's 3-1-1 rule requires that any liquid container in your carry-on must hold 3.4 oz (100 ml) or less, and all containers must fit in a single quart-sized clear zip-top bag. The challenge with snow globes is that the liquid is sealed inside the globe itself — you cannot pour any out to get under the limit.

The Tennis Ball Test

The TSA uses a practical rule of thumb for snow globes at the checkpoint: if the snow globe appears to hold more liquid than a standard tennis ball, it is not allowed in carry-on. A tennis ball has a volume of approximately 100 ml — conveniently matching the liquid rule threshold.

What passes this test:

• Very small decorative globes (golf-ball-sized or smaller)
• Miniature souvenir globes often sold in airport gift shops
• Small ornamental globes with very little liquid visible

What fails:

• Standard commercial snow globes (most common sizes)
• Decorative globes with wide bases filled with liquid
• Any globe where the liquid chamber is clearly larger than a tennis ball

Even globes that appear borderline are subject to officer discretion. If a TSA officer is unsure, they may use a manual check or simply deny the item. You cannot reliably predict which way a judgment call will go, which is why the safest rule is: if in doubt, check it.

The Safest Approach: Always Check Snow Globes

For any snow globe larger than a golf ball — and frankly, for any snow globe you care about — put it in your checked luggage. There is no risk of confiscation in the cargo hold, no judgment calls at the checkpoint, and no stress at the security lane.

When packing a snow globe in checked luggage, protect it properly:

• Wrap it in at least two layers of clothing or bubble wrap
• Place it in the center of the bag, surrounded by soft items on all sides
• Do not put it near the edges of your suitcase where impact damage is most likely
• If the globe has a fragile base or is a high-value collectible, place it inside a rigid container (a shoe box works well) before placing it in your bag
• Consider sealing it in a zip-lock bag in case the globe leaks under cargo pressure changes

The Airside Purchase Trap

One of the most common snow globe mistakes is buying one at an airside gift shop — a shop located after the security checkpoint — and then encountering a problem at a connecting airport.

Here is what happens: You fly from City A to City B, buying a snow globe at the gift shop in City A after clearing security. You board your flight with no issues. At City B, you have a connecting flight that requires you to clear security again. Now your snow globe has to go through the checkpoint — and if it is larger than a tennis ball, it will be confiscated.

This is a particular issue on:

• US domestic connections after an international arrival (you re-clear customs and security)
• Any connection in a country where you must pass through security again
• Multi-leg trips where you need to transit through a hub airport

If you buy a snow globe airside and face a connection that requires re-screening, you have limited options: mail it home from the connecting airport, check a bag specifically to hold it, or risk losing it at the next checkpoint.

TSA's Own Warning

The TSA specifically lists snow globes in its "What Can I Bring?" guide and flags them as a frequently confiscated item. The agency recommends packing all snow globes in checked luggage regardless of size, to avoid delays at the checkpoint and the risk of confiscation.

This is one area where following TSA's own recommendation is clearly the right call. The inconvenience of unpacking a snow globe from your carry-on during screening — or worse, watching it get thrown away — is not worth the flexibility of carrying it on.

International Travel Considerations

Outside the US, the same 100 ml liquid rule applies across most countries that follow ICAO aviation security standards. The UK, EU, Australia, Canada, and most other major aviation markets all enforce some version of the liquid container limit. Some countries may not have the TSA's specific tennis ball guidance, but any security officer who identifies liquid inside a container will apply their national liquid rules.

If you are traveling internationally with a snow globe souvenir, checked luggage is the right choice regardless of which countries you are transiting through.

Quick Reference

The bottom line: snow globes and airport security are a bad combination. Pack them in checked luggage, wrap them well, and you will never have a problem.
