If you or your kids love playing with slime, you may be wondering if you can bring it on an airplane. With its gooey texture and potential messiness, slime raises some questions about what’s allowed through airport security.

We’ll give you a quick answer upfront: Yes, you can bring slime on a plane as long as you follow TSA rules on liquids and gels.

In this comprehensive guide, we’ll go over TSA policies, tips for traveling with slime, whether you can make slime on a plane, and answers to other common questions about flying with the sticky stuff.

TSA Rules for Flying with Slime

Slime Subject to 3-1-1 Liquids Rule

If you’re wondering whether you can bring slime on a plane, the answer is yes! However, there are some rules and regulations you need to be aware of.

The Transportation Security Administration (TSA) has specific guidelines in place for carrying liquids through airport security, and slime falls into this category.

According to the 3-1-1 liquids rule, all liquids, gels, and aerosols must be in containers of 3.4 ounces (100 milliliters) or less, and all containers must fit into a single quart-sized, clear plastic bag.

This means that if your slime is in a container larger than 3.4 ounces, you’ll need to pack it in your checked bag.

Slime Must Be Packed in Checked Bag If Over 3.4 oz

If your slime exceeds the 3.4-ounce limit, it must be packed in your checked bag. This is because liquids in containers larger than 3.4 ounces are not allowed in carry-on bags.

So, if you want to bring a larger container of slime with you on your trip, make sure to pack it securely in your checked luggage.

It’s important to note that the TSA may inspect your checked bag, so it’s a good idea to pack your slime in a leak-proof container and place it in a plastic bag to prevent any potential mess.

Slime Could Face Additional Screening

While slime is generally allowed in both carry-on and checked bags, there is a possibility that it may undergo additional screening at the security checkpoint.

This is because the consistency and appearance of slime can sometimes resemble prohibited items or substances.

To avoid any delays or issues, it’s recommended to pack your slime in a clear, resealable bag and declare it to the TSA officer at the checkpoint. By doing so, you can help facilitate the screening process and ensure a smooth travel experience.

Tips for Traveling with Slime

Traveling with slime can be a fun and entertaining way to keep yourself or your children occupied during a long flight. However, it’s important to follow certain guidelines to ensure a smooth and hassle-free travel experience.

Here are some tips for traveling with slime:

Pack Slime in Resealable Plastic Bags

When packing slime for your trip, it’s crucial to keep it contained and prevent any spills or leaks. One way to do this is by packing your slime in resealable plastic bags. These bags are durable and will help prevent any messes in your luggage.

Make sure to squeeze out any excess air from the bag before sealing it to prevent the slime from expanding and potentially bursting during the flight.

Keep Slime in Your Carry-On Bag

If you’re planning to bring slime with you on the plane, it’s best to keep it in your carry-on bag rather than checking it in with your luggage.

This way, you can easily access it during the flight and ensure that it’s handled with care.

Remember to comply with the TSA regulations regarding liquids and gels, as slime may fall under these categories. Check the size restrictions for liquids and gels to ensure your slime is within the allowed limits.

Bring Slime Toys and Activities

In addition to bringing slime, consider packing some slime toys and activities to keep yourself or your children entertained during the flight. This could include small containers, molds, or even small figurines that can be used with the slime.

These extra items can enhance the sensory experience and make the travel time fly by faster. Just make sure to keep any additional toys or activities within the appropriate size and weight limits set by the airline.

Remember, it’s always a good idea to check with your airline and review their specific rules and regulations regarding the transportation of slime or any other substances.

By following these tips and guidelines, you can bring your slime on a plane and enjoy a fun-filled journey to your destination!

Can You Make Slime on an Airplane?

If you’re a fan of slime and planning to take a flight, you might be wondering if you can make slime while onboard.

While it can be a fun and entertaining activity, there are a few things to consider before attempting to make slime on an airplane.

Slime Ingredients Allowed in Carry-On

When it comes to making slime on an airplane, the Transportation Security Administration (TSA) has certain regulations in place regarding liquids and gels.

While most slime recipes require liquid ingredients such as glue and activator, these are typically considered to be in compliance with the TSA’s rules for carry-on liquids.

However, it’s important to ensure that these ingredients are stored in containers that are 3.4 ounces (100 milliliters) or less, and that all containers fit within a single quart-sized plastic bag.

It’s also a good idea to label the containers to avoid any confusion during the security screening process.

It’s worth noting that some airlines may have their own specific rules regarding liquids and gels, so it’s always a good idea to check with your airline before bringing slime ingredients on board.

Challenges of Making Slime During Flight

While it may be technically possible to bring slime ingredients on an airplane, actually making slime during the flight can present some challenges. One of the main obstacles is the limited space available on most airplanes.

Slime-making requires a certain amount of room to mix and knead the ingredients, which can be difficult to achieve in the cramped space of an airplane seat.

Additionally, the turbulence experienced during flight can make it challenging to create slime without making a mess.

It’s important to consider these factors before attempting to make slime during your flight.


With some smart packing and preparation, you don’t have to leave your slime at home for your next flight.

By following TSA guidelines for gels and liquids, containing any messes, and keeping your kids engaged, flying with slime can be smooth. Safe travels and happy sliming!
