Understanding Ocean Currents with a GPS-Enabled Bottle

The video follows a team as they launch a bottle into the sea from Brittany, aiming for it to reach England. They discuss the influence of local currents, tides, and the Gulf Stream on the bottle's journey. A tracker inside the bottle allows them to monitor its path, which zigzags due to tides and wind. After eight days, the bottle covers 360 kilometers. The team retrieves the bottle, demonstrating how understanding currents and wind can guide objects across the sea.

What technology is used to track the bottle's location?

What was the distance traveled by the bottle after eight days?

What conclusion can be drawn about the bottle's journey based on the currents and wind?
