Want to take a walk underwater?

Quote: Researchers have developed a 3D-printed smart gel that can walk underwater and even grab and move objects. The development paves the way for innovations in medicine, robotics, and devices that can be used underwater. A team of engineers from Rutgers University developed the material, which they said can not only self-actuate when submerged in water, but even bump into things without damaging them. Endquote
