DARPA, the Defense Advanced Research Projects Agency, has developed new paddles that allow users to climb vertical walls like Spider-man. For the first time in history, a fully-grown person climbed a glass wall more than two stories in the air.
The Z-man program aimed at designing a new tool for soldiers to use when climbing walls. Traditionally, fighters in wartime have had to rely on ladders and ropes to overcome vertical surfaces. These are both noisy and bulky, making it difficult for warriors to climb quietly when needed.
