Can You Bring Slime On A Plane? (TSA Rules)

Last Updated on October 24, 2021

Here’s the deal about flying with slime…

Is slime considered a liquid by the TSA?

The TSA often says, “If you can squeeze it, smear it, pump it, spread it, spray it, or spill it then it’s considered a liquid”.

Slime definitely falls into that category.

Let’s see what the rules are about taking slime on your next vacation.

TSA Slime Rules

The Transportation Security Administration doesn’t mention slime specifically on their website.

They do however frequently mention that liquids are restricted in carry-on bags.

Slime is considered to be a liquid by the TSA.

That means that while you can bring slime on a plane in carry-on luggage the maximum size container is 3.4 oz.

Slime also needs to be packed in your one quart-size liquids bag. So are you willing to sacrifice your shampoo to bring slime in hand luggage instead?

You can only fit so many travel-size liquids in that little ziplock plastic bag.

You could pack slime in checked bags but then the fees for checked luggage can be quite high.

Still Unsure? Ask The TSA On Twitter

You can ask the TSA about bringing anything on Twitter.

Brad asked the TSA if his daughter could bring slime in her personal bag:

Krish asked if this 3.5 oz slime would be allowed through the security checkpoint:

Unfortunately, if the TSA officer reads the label that it’s 3.5 oz then it would not be allowed through security. The maximum is 3.4 oz. They might not notice it.

This may help someone.

Most DIY slime is made using Elmer’s school glue. The regular school glue is a liquid too, but there are recipes for DIY slime that use Elmer’s stick glue.

Since stick glue non-flammable and a solid it’s allowed in carry-on luggage in unrestricted quantities.

So perhaps instead of taking slime on a plane, you could take the materials to make slime. You’d only need space in your quart-size bag for a little bottle of food coloring.

If you can bring solid materials and you simply need to add water to the mixture at your destination then maybe that’s a way to have fun traveling with slime.

I’m no slime-making expert but have a search around I’m sure it could be done.

Mark wanted to bring this DIY slime on the plane:

He says it was made using contact lens solution. As it happens, contact lens solution is exempt from the liquids rule because it’s seen as a medically necessary liquid.

You wouldn’t need to tell airport security that you were really bringing the contact lens solution to make slime!

I’m sure shaving cream foam could be replaced by a solid shaving cream bar too.

You know what they say. Where there is a will there is a way!

The Verdict

You can bring small quantities of slime in your carry-on bag.

It must be in containers that are 3.4 oz maximum. And all those containers must be packed in your quart size bag.

If you are not bringing any other toiletries at all then you might be able to bring 7 or 8 little bottles of travel-size slime in your hand luggage.

Failing that, you’ll need to bring dry materials to make your own slime once you reach your destination.

Or pay the fee to bring a checked bag that can be entirely full of slime if you don’t pack any clothes!
