A FLIGHT attendant has revealed a unique way to get around the strict liquids cap at airport security.

The American cabin crew member suggests freezing any liquids, so that they show a solids when your hand luggage goes through scanners.

She told Yahoo! News: "If you have an important liquid, but you don't want to pay to check a bag, it's worth trying to freeze it so it goes through the security scanner as a solid.

"Even if it melts a little bit on the ride to the airport, it shouldn't be a problem as long as it's stored properly."

According to America's TSA (Transport Security Administration) website, the rule is official.

They explain: "Frozen liquid items are allowed through the checkpoint as long as they are frozen solid when presented for screening.

"If frozen liquid items are partially melted, slushy, or have any liquid at the bottom of the container, they must meet 3-1-1 liquids requirements."

The 3-1-1 rule is the USA's name for all liquids being under 100ml if taken onboard as carry-on luggage.

The former flight attendant also suggests taking an empty water bottle with you.

She explained: "Most airports are full of water fountains, and many even have a special pump to refill bottles quickly.

"To keep your bottle full during the flight, just ask your flight attendant for a refill. If you're lucky, they may even put ice in it."

In the UK, all liquids must be under 100ml at airport security, or they will be confiscated.

Any liquids you are taking through airport security must be placed in a single, transparent, resealable plastic bag, which holds no more than a litre and measures approximately 20cm x 20cm.

Liquids in containers larger than 100ml generally cannot go through security even if the container is only part full.

There are some exemptions including items needed for essential medical purposes, baby milk and any dietary requirements.

Savvy travellers are always finding more ways to make the most of their precious luggage allowance.

Innovative companies are now selling items that would normally come in liquid form as a hard block, meaning that it doesn't have to take up space in your precious plastic bag.

Leading the charge is Lush, with their new cruelty-free shampoo bars.

The bars  are said to last between 80 and 100 washes, doing the job of three 250g bottles of liquid shampoo, and cost just £6.25.
