Booking a holiday can be exciting. You wait months for the day to arrive when you have to travel to the airport and something about that whole experience is exhilarating. Now one woman who was travelling via Heathrow Airport couldn't believe what happened when she attempted to take 2 litres of liquids onto the plane.

Now posting on TikTok, the traveller tried her luck despite for years the limit being just one twentieth of that amount. That's because at several UK airports the rule has actually been removed, meaning passengers can now take water bottles, toiletries and other liquids on board without worrying about having them confiscated.

The user, who posts on the video sharing platform under the username Khoslaa, admitted she was worried about the test, noticing there was a heightened security presence that day, as well as more travellers than she was used to.

Incredibly, the influencer failed at the first hurdle, deciding to ditch her 2L bottle and instead try the experiment with a 125ml bottle of hairspray, claiming she was finding the extra volume "too heavy".

Despite not seeing any signs saying the rule had been changed, Khoslaa bravely decided to plough on though she felt "nervous", even going as far as ignoring a 'no camera' sign in order to record her experiment.

At the moment of truth, Kholslaa watched on as her bag rolled through the X-ray scanners, in footage that can only be described as totally gripping.

And the result? Success! both Kholslaa and her hairspray made it through unscathed. The reactions to the video were mixed, with many confused as to how she managed to slip through airport security unquestioned.

Meanwhile, another joked that returning to the UK with the liquid may be tricky, writing "Good luck coming back with it though."

Some Heathrow Airport terminals allow you to take up to two litres of liquid through security – but you must check the rules before flying.

For terminals 2, 3 and 5, the policy states: "Liquids, aerosols and gels can now be packed in your cabin bag, and are permitted in containers up to 2 litres. These do not need to be removed."

However, terminal 4 has different rules. The website adds: "Liquids, aerosols and gels can be carried in containers up to 100ml. These must be placed in a transparent, re-sealable plastic bag, no bigger than 1 litre capacity.

"The maximum dimensions of the bag are: 20cm (8 inches) x 20cm (8 inches) and you must be able to close it. We allow one liquid bag per person."
