We’ll start with the basics. If you’re making tea in a flask, it’s surprisingly easy to end up with something bitter and curdled. Tea Guardian (no relation) has a useful guide. Brew the tea in a different receptacle before you pour it into a preheated flask. And always, if you can, take a separate container of milk. You could choose a tea that doesn’t require milk: Thermos itself has a recipe for rosemary green tea that is what it says – green tea, infused with a stalk of rosemary. A third, caffeine-free option is turmeric tea: turmeric, ginger and orange, steeped in boiling water and strained.

The problem with flasks, however, is that they are blatantly obvious and you aren’t actually allowed to take your own alcohol into bars at all! So… if you’re feeling a little mischievous, or simply just fancy a drink during the day (I won’t judge), why not consider a hidden flask? The hidden flasks I am going to review in this list all take the appearance of a normal item that you would most likely bring around with you during a normal working day. Yes, some of them you may not get into a bar, but if you need a drink during the day whilst you’re out and about, or on holiday, why not consider some of these concealable hidden flasks? There are a variety of different ties to choose between in terms of colour and size, as BAXBO, the manufacturer, really have tried their best to cater to different styles and body types. You don’t even need to use this flask for alcohol either, sometimes it’s hard to carry around a water bottle, especially if you’re wearing a suit, so why not keep some of the water within the tie and have a drink when you need to. Liquid medicines: You are only permitted to carry quantities of liquid medication in excess of your personal liquid allowance where it is needed during the course of your flight. All medication should be accompanied by documentary proof of authenticity, such as a prescription or letter from a medical practitioner confirming that you need them for your journey. Liquid medication that is not required on the flight should be carried as hold luggage.

Coffee Detectives recommends filling your flask with hot water, taking a French press mug with you, and making a fresh cup every time. If you want to mix it up for the season, then do as Hedgecombers does and add the ground seeds from four cardamom pods to your coffee before you press it.

You need to make sure that you don’t bring attention to yourself when using your hidden flask. If you are caught drinking from something which is blatantly fake, you may be questioned on what you are drinking, even if it is just water. Make sure that the flask is well hidden at all times to avoid prying eyes. Get your story straight: This includes crowbars, drills and drill bits, saws, blowtorches, bolt guns, nail guns, or any tool with a blade or shaft over 6cm (eg screwdrivers or chisels).

We're happy to accommodate whenever possible.One key thing to remember is to always keep your story straight. What I mean by this is that if you are caught with one of the hidden flasks above, you must have a believable story as to why you have that particular item with you. If you are believable enough, no further questions will be asked. What else can you use a flask for? We’ve all been there before, you go on a night out, spend a little too much money, and find that your bank account has seen brighter days in the morning. Many individuals will go out of their way to try and make their night a little cheaper by finding cheaper ways to consume beverages. Whether that’s sneaking alcohol into a bar, chatting to somebody for drinks, or hiding alcohol within a flask, there are a variety of different ways to do it. The actual brand name “rain and shine” is believable in itself, so I highly doubt you will be questioned upon arrival. If you are just using the flask to drink during the day though, please do be aware that you may receive some funny looks when somebody spots you drinking out of what they thought was an umbrella!

The GoPong Rain or Shine Umbrella flask really is a godsend when it comes to hiding beverages. For starters, you receive two different realistic looking umbrellas which both hold 12oz of liquid each, which when you have two of them, is more than enough to get you through the day. Most people tend to carry umbrellas with them during the day and even on nights out, especially when you live in a rainy state or country, so there is no way that you could possibly be questioned about them. A single cigarette lighter is allowed and must be placed in a re-sealable, plastic bag along with your other liquids. (See Liquids 100ml rule above).Including stun guns, Tasers, animal killers, incapacitating chemicals, gases or sprays (eg Mace), pepper sprays, tear gas and animal repellent sprays. Tools Now, to more adventurous fare. There’s something pleasingly medicinal about the taste of ginger tea. A good basic recipe can be found on A Day in the Kitchen, but it is really just chopped ginger boiled in water and sweetened with honey. The Umbrella is manufactured with food-safe materials and includes a mess-free pouring spout so that you can easily insert your choice of beverage within.
