A drone or a submarine? 🫧

A student just built a drone that flies through the air and swims underwater — and it actually works.

As part of his Bachelor’s project, Andrei Copaci created a 3D-printed, hybrid drone with variable pitch propellers, meaning the blades shift mid-flight to adapt between air and water.

Just a laptop, a printer, and a smart idea.

The drone is fully custom-coded and transitions seamlessly between flying and swimming.

We're entering a new era, where curious students can prototype what once took massive funding and R&D efforts.
