Now, you might be wondering, why the 3.4 ounces limit? Is it because that's the exact amount of lip balm the average person uses on a flight? Nope! It's actually because the TSA wants to prevent explosive liquids from being smuggled onto planes. Who knew hair gel could be so dangerous?
But, here's the thing: not all liquids are created equal. Some, like breast milk and formula, are exempt from the 3-1-1 rule. Yep, you read that right - breast milk is like a special kind of liquid gold that gets to bypass the rules! Meanwhile, water is a no-go, unless you buy it after passing through security. Talk about hydration hysteria!
So, what's the max ounces for carry on when it comes to beverages? Well, it's a bit of a gray area. The TSA says you can bring an empty water bottle through security, but you'll need to fill it up after passing through the checkpoint. But, what about coffee or juice? Can you bring those in your carry-on? The answer is... maybe! It depends on the airport and the airline, so be sure to check ahead of time.

Now, let's talk about the fun stuff - like makeup and perfume. These liquids are subject to the 3-1-1 rule, but there are some creative workarounds. For example, you can decant your favorite fragrance into a travel-sized bottle to avoid checking a bag. And, if you're feeling extra adventurous, you can try making your own solid perfume to avoid the liquid limit altogether!
