Hydration drink Prime has been flying off shelves in the UK.
The viral hydration drink, created by YouTube stars KSI and Logan Paul, has gone viral as kids are desperate to purchase it. However, with the drink only available in Asda in the UK, the shop is having to limit sales to keep up with demand.
But when children are lucky enough to spot the popular drink - which comes in different flavours, including Lemon Lime, Tropical Punch, Ice Pop and Blue Raspberry - will they actually be able to make a purchase?

Many retailers will ask those under the age of 16 to produce ID before allowing them to buy an energy drink. This is because high levels of caffeine can be bad for youngsters. Here is everything you need to know about your child buying an energy drink.
What are energy drinks?
According to the Association of Convenience Stores (ACS) the legal definition of energy drinks is dependent on the amount of caffeine per litre, with the threshold being 150mg of caffeine per litre.
If an energy drink has 150mg of caffeine per litre (mg/l) it must be labelled to say: "High caffeine content. Not recommended for children or pregnant or breastfeeding women.”
The label must also include the caffeine content of the product in mg per 100ml. Energy drinks are not sports drinks which are specifically designed to help athletes and other active people hydrate before, during and after exercise.
Can someone under 16 buy an energy drink and do they need ID?
There are no legal age restrictions on the sale of any caffeine containing foods and beverages, including energy drinks in the UK. Likewise, there is no legal requirement for children under 16 years old to produce ID either.
However, stores can implement their own policies, restricting the sales of such products to children. Back in 2018, many supermarkets such as Tesco, Waitrose, Sainsbury's, Aldi, Asda, Morrisons and Lidl all banned the sales of energy drinks to people under the age of 16.
Meanwhile there are advertising rules and regulations in place around energy drinks. Since 2010, the BSDA has operated a voluntary Code of Practice agreeing not to market or promote products to under 16s.
Are energy drinks safe to drink?
British Soft Drinks Association said: "Energy drinks and their ingredients have been deemed safe by regulatory authorities around the world. Energy drink manufacturers have taken all possible steps to be clear about the suitability of energy drinks. Retailers, schools and parents all have a role to play in educating children about caffeine and sugar consumption from all sources."
