Freediver has people ‘freaking out’ as she shows what it’s like going through tight spaces

Ariel, you better watch out because it looks like there's another mermaid in town.
Known as 'Kendra The Florida girl' on social media, the woman often documents her underwater adventures and what kind of things she sees.
In one video in particular, Kendra's been hailed as 'badass' as she casually slipped through an extremely tight space.
And if you're claustrophobic (like me), it will send a shiver down your spine.
Check it out:
The video has amassed over 275,000 views on TikTok, and people have labelled it as 'terrifying'.
One person penned: "Underwater + enclosed space = terrifying."
"Never in a million years," said another - and I can't help but feel the same.
"Respect! I'm dying just from watching!" added a third, while another person said she had a 'mini panic attack' just watching.
"I'm freaking out just watching it," penned one user.
But Kendra insists it's not actually that bad and that she always makes sure she's safe.
"It’s definitely not something I recommend anyone to do," she responded to one person, and added that she's 'always safe'.
Replying to someone who asked what would happen if she were to get stuck, Kendra assured them that she has 'safety divers in place'.
Elsewhere she said that she's 'had a lot of training'.
Other videos on Kendra's TikTok show her doing similar swims, and it's safe to say she's been to some amazing places.
But in her bio, she tells people that she doesn't disclose the locations of her deep-dives.
In another video of Kendra swimming through a tight space, she put The Little Mermaid track 'Part Of Your World' over it, in the nod to her mermaid-like skills.
"I had no idea people dove in caves without tanks!!" someone replied to the viral clip.
"You guys are BADASS! Showing the world things we didn’t know our bodies could do!!! Wow!"
While it's impressive that Kendra's able to hold her breath for a long period of time, for people who aren't properly trained it can prove extremely dangerous due to the affect it has on your lungs.
When you reach certain depths, the amount of air in your body is crushed down by the water pressure. A video shows how the pressure impacts one litre of air in a container.
Even at a relatively shallow depth of 55 metres, the air is crushed right down to a fraction of how it started, just 154ml - so less than a sixth of its volume at the surface.
This is 55 metres down. The current world record for highly dangerous 'no limits' free-diving was set by Herbert Nitsch in 2007, and it is 214 metres. For perspective, photosynthesis becomes largely impossible after around 100m due to not enough sunlight.
I struggle to hold my breath just to get rid of the hiccups, never mind swimming underwater.
