Friendship can blossom in the most unexpected places—sometimes, it just needs a little push from the ocean’s currents.

Amy Bisterzo and her 10-year-old son, Lorenzo, decided to embark on a brief jet ski adventure in the Atlantic Ocean, near their home in Old Fort Bay, Bahamas. As part of a playful experiment, they tossed a message in a bottle into the vast waters, as reported.

Inside the bottle was a simple note sending cheerful greetings to its future finder, revealing its origin, the date—February 10, 2025—and Amy’s WhatsApp number, just in case someone wanted to reach out.

Initially, their minds were abuzz with excitement and endless possibilities.

“When we first released it, we were thrilled, imagining all the adventures the bottle might have and the distant shores it could reach,” Bisterzo shared with SWNS, as reported by Good News Network. “But truth be told, as time passed, it slipped from our minds entirely.”

Reflecting on the fun gesture, she admitted, “In my adult thinking, I knew the chances of it being found were slim.”

But she was wrong.

A year later, Bisterzo got a shocking phone call that reeled her right back in.

Turns out the bottle went on a 4,000-mile voyage before washing ashore 12 months later on Vila Chã Beach in Portugal, and it was shore luck that schoolteacher Maria Enes spotted it while she was walking her dog.

Enes said finding a mysterious bottle in the sand was like a “childhood fantasy,” and took it home.

“I took the paper out with tweezers and I was astonished that it came from the Bahamas, exactly one year had passed,” said Enes, 49.

Enes immediately picked up the phone and punched in Amy’s WhatsApp numbers.

When Bisterzo answered, she was astonished to read the message, “I found your bottle.”

“I shouted upstairs to Lorenzo, ‘Someone found our bottle,’ … it was so long ago he didn’t know what I was talking about and then I showed him,” said Bisterzo. “Then I started to communicate with Maria, and she sent voice notes and videos, and very quickly I realized this woman was so kind and lovely.”

Now, this unexpected friendship is making waves in all of their lives — and the new pals are hoping to meet up in the future.

“I never thought it would be found, let alone almost to the year exactly, let alone go so far and also to be found by the perfect person,” said Bisterzo.

Enes even has an idea for when they do: throw another bottle into the ocean together and find a new friend to add to their group.
