Other than firemen, the military and masked vigilantes, there probably isn’t a huge market for a suit that allows you to scale up walls. However, Italian scientists have calculated how much stickiness a suit needs to mimic the ability of insects and spiders to climb up a wall without peeing their pants in fear of falling. Unless the suit injects a good bit of teen angst and pudginess (if this was the third suit in a trilogy), we’ll have no part of it. [Telegraph]
