Most people can't imagine living under water.
But German engineer Rüdiger Koch's trying to break the current Guinness World Record of 100 days.
Koch is hoping to remain there for 120-150 days.
His accommodation is an underwater room, 11 metres down.
He's in a "SeaPod", near the coast of Panama.
Koch and his team hope to show it's really possible.
The room where Koch is staying is environmentally-friendly.
It's a place which fish and other creatures can live on.
Meanwhile, Koch's team is based in a larger, round pod above water.
Koch's company, Ocean Builders, created it all.
They hope to get people thinking about living underwater, a sustainable way to live.
In future, it could be a human habitat.
Koch has to stay under water continually to break the record, and all his activities are checked.
He'd love to get into the sea and dive, so his team are working on creating a special window.
Meanwhile, Koch has some time left in his underwater room.
He's been there since 26th September and will only come out on 24th January 2025.
