KSI 'tells' young fan the first two things he should buy after winning £400,000 gold PRIME bottle

KSI 'told' a young fan the first two things he could buy after he cracked the code to win a £400,000 solid gold PRIME bottle.

To celebrate one billion sales of the hydration drink, KSI and business partner Logan Paul announced a one-off competition on Friday.

Two solid gold bottles of PRIME were placed in different locations - one in London and one in New York - and fans were given 48 hours to find them before they were destroyed.

Each bottle was placed behind a bulletproof case, and were locked by a six-digit code.

Nobody in New York was able to crack the code, meaning Paul had to stand by and watch as the bottle was incinerated. You can see the clip below.

The bottle in London, however, was successfully won by a young boy, with KSI on hand to witness the moment the code was cracked.

In a video showcasing the moment, KSI asked: "Alright, is it gonna be this one?"

After the code was entered, the room was engulfed by green lights and confetti, with the social media star exclaiming: "Oh my God, we have a winner in London!"

The lucky winner was accompanied by his mother, and the pair shared a photo with another relative after he won the solid gold bottle.

The photo was shared on social media and picked up by KSI, who 'advised' the youngster on the first two things he should buy with his £400,000 winnings.

He said: "The amount of PRIME and V-bucks they're gonna get will be unreal."

V-Bucks is the digital currency used within the popular Fortnite video game, for which users spend real money to be able to buy in-game items in the game's different modes.

And while there couldn't be two life-changing winners of the solid gold PRIME bottle, there was at least one - and they got to meet KSI in-person as well. As afternoons go, it wasn't a bad one.
