00:00By creating a shape-shifting wheel, researchers in South Korea may have improved upon one
00:06of mankind's most important early inventions.
00:11This first-of-its-kind technology can change how rigid a wheel is, making it easier for
00:15devices like wheelchairs to climb stairs and rugged paths.
00:20Researchers say that when they put their plan in motion, the goal was to move away from
00:23traditional designs.
00:24The inspiration for the design came after researchers studied the way that water droplets
00:52hold their shape due to the amount of surface tension they have.
00:56Using this concept, the wheels can firm up or soften, depending on the obstacles or the
01:02environment.
01:03Although it's still too early to tell just how effective the wheels will be in everyday
01:28life, researchers say they have a lot of potential.
01:31The plan now is to continue testing the technology before making it public, ensuring these wheels
01:36are all-around the best.
