While the weather isn't looking like it, we are in summer and - hopefully - we're gonna see a nice bit heat in no time.
And when the weather gets warmer, it's always a shout to make sure you're keeping hydrated and chugging back that water whenever you can.
Now, it doesn't matter if you're a Stanley cup stan or more of a Hydro Flask kinda gal, we've probably all noticed that water bottle caps are all different colours whenever we nip out to the shops.

One woman, who by goes the handle @sasha.mints online, took to TikTok to share her pearl of wisdom.
In the short clip, the DIY and Life Hacks aficionado explained that a white lid indicates that the water has been 'processed', while green signifies that 'flavour has been added'.
Meanwhile, the blue cap symbolises 'spring' water with the black cap pointing to the water being 'alkaline'.

Sasha captioned the video: "All the things you learned from TikTok."
People have since rushed in to share their praise for the explanation with one TikTok user writing: "Ohh that’s smart I never knew that!!"
"Wow," remarked a second, while a third quipped: "Wuttttt. I had no idea! No I’ll be looking at ALL the caps!"

Another added: "Thank you for this babes!"
And a final TikTok user echoed: "Wow I had no idea!"
Us neither!
So, to summarise:
- White caps indicate water that's been treated through advanced purification methods.
- Blue caps contains natural spring water, bringing you a taste of the great outdoors.
- Black caps are for alkaline water with a higher pH level, offering potential health benefits.
- Green caps are for infused or flavoured water for a little something different in each sip.
Of course, the whole rainbow system may differ from country to country - so be sure to look into the bottle cap colour code specific to where you live to get a more accurate idea of what they symbolise.

You may have also recently noticed that a load of bottled beverages now have a new lid design that sees the caps attached to their plastic bottles.
Coca‑Cola Great Britain (CCGB) said it is trying to make 'it easier to recycle the entire package and ensure no cap gets left behind'.
A spokesperson for Coca-Cola told LADbible: "Coca-Cola’s new attached caps are designed to prevent litter, and make collection and recycling easier by keeping all parts of the bottle together.

"We understand that it’s a bit of a change, however extensive research went into the new design to ensure consumers continue to have a positive experience when enjoying our drinks.
"When opening and closing the bottle, we advise consumers to not remove the cap from the bottle neck, or twist or bend the tab in a way that could compromise or damage the closure."
