This happened last month but it's making the rounds now. A group whale watchers were in the waters near Canada, and it is the trip of their lifetime I bet.
The video starts as they're next to three whales that have surfaced right next to their boat.
Then, ALL THREE whales dive at the same time. They're under water for around 10 seconds and then, one at a time, each one leaps into the air and spins as if they're synchronized swimmers.
