It was a hot sunny day in July and Mary with Alex were on a beach in Halkidiki. This was the third day of their holidays.

They had already eaten their fresh fruits!

 While they were enjoying the sunset, they saw something floating in the sea in front of them.

It was an old bottle and something was inside it. It looked like a piece of paper. What was it??

Come on, Alex! Let's see what's inside the bottle!

On the paper  something is written:

Follow the clues to find the treasure! 

You have to pass a message to others to improve their lifestyle with an action. If you complete the puzzle you will find the treasure! 

The Spanish Know...

Wow!!!

Thank God we know some kids from Spain!!

Quickly!!!

Let's go home to contact our friends!

I wonder what it is all about!!

Friends from Spain found the bottle when they walked along the Guadalquivir river in Sevilla.

They were very surprised because they were not used to seeing a bottle in the river, so they went to get it.

They went to the Police office in "La Plaza de España" to be advised about what to do. The policewoman said the person who received the bottle should send it to another friend. 

The Romanian students were at their school, wondering what was the secret message that they had received from their Spanish Friends.

While they had Easter celebrations, they couldn't stop wondering what the secret message was. They prepared their healthy easter recipes and decided to find someone to help them.

They traveled around the country to find some clues. They arrived at Peleș Castle, but nobody could help them solve the mystery.

There was no clue at Bran Castle, where mystery prevails. The 4 images from the bottle were very familiar. They decided to send the message to their Cypriot friends.

Find the clue and complete the puzzle.

What is this?

Let's find out!

The Cypriot friends were swimming at Nissi Beach when they found the message in the bottle.

Can you help us ?

They asked the people by the beach but.. nobody knew.

When they went to Medieval Monastery they noticed the puzzle pieces... and then they knew what to do!

They sent all the clues to their friends at Evosmos, Thessaloniki, Greece.

 The students of the 13th Primary  school of Evosmos found the bottle during a school visit to the city centre of Thessaloniki. They were on a walking tour of the Byzantine monuments and ended up at the White Tower on the city's  seafront, to rest and have some snacks.

They were sitting on the benches, eating "koulouri" and their homemade sandwiches when they saw a seagull holding the bottle in its mouth. They rushed to pick it up and open it curiously.

We don't know!!

Guys...what is this paper inside the bottle?

There are some pieces of a puzzle. They are the clues to find a treasure!!!!!

?

?

The puzzle pieces looked familiar to them but trying to understand the meaning of it they were getting more confused...!

On the way back to school they couldn't get it out of their mind.

We need some help!

Let's ask our fellow students of the 23rd school.!!!!!
