VSL:SCIENCE // The best video you’ll see today

We all know how smart, playful, and inventive dolphins can be — but it isn’t often that we get to see one of their actual inventions. That’s what makes this video footage of the dolphins at Sea World, in Orlando, so remarkable.

These dolphins tip their heads and expel brief bursts of CO2 through their blowholes; internal forces break the bubbles’ centers open to create tightly structured, spinning rings. The dolphins then flip the rings around, poke their noses through them, twirl them into different shapes — they even bite them in half. It’s one of the best shows in Orlando today, and these aquatic impresarios thought it all up on their own.
