Your Messega in a Bottle
FOUND A MESSAGE IN A BOTTLE AND UNSURE WHAT TO DO? It’s simple! Take out your smartphone and note the coordinates where you found the bottle. Then, write the coordinates on the message (there’s a dedicated line for finders) with a pen. Next, take a photo of the message (with your coordinates on it) and email it to aquaticplastic@petkupa.hu. After sending the email, place the message back in the bottle and leave it as it was, allowing it to continue its journey. Why? Find out in the project description below!

ARE YOU INTERESTED IN CITIZEN SCIENCE & ALWAYS WANTED TO SEND A MESSAGE IN A BOTTLE?

You’ve probably heard about the Great Pacific Garbage Patch. But did you know that 80% of all marine litter reaches the oceans through rivers? We can all agree that keeping our rivers clean and plastic-free is important for everyone. To make a real difference, we need to better understand how pollution travels along our rivers. That’s where not only technology but citizen science can help. We invite anyone to become a citizen scientist and help us track pollution by sending a personalized message in a bottle. Plastic Cup Society, during its many years of operation, has recovered and preserved dozens of messages in bottles—containing love letters, farewells, wishes, coins, pebbles, and, most importantly, valuable information. These messages reveal how long bottles spend in the river, how far they travel, and where they originate—insights that inspired us to launch this citizen science campaign. So far, schools and NGOs from five Danube countries have joined. If you’re interested in making a positive impact, simply download our Invitation Handout! This document and video below contain all the details you need to get started, and don't forget to check out our map for the bottles already released and fund!
