10. Wall Climbing like Spiderman
The military wants to be able to send soldiers up and over high walls, and sometimes grappling hooks aren’t practical. What to do? How about a vacuum backpack with suction gloves that’ll let you climb up brick, glass, or pretty much whatever?
Utah State University “Ascending Aggies” team recently won first prize out of 33 teams in the Air Force’s contest to get four soldiers over a very tall wall. It’s the lead climber that’s the tricky part, see. The Ascending Aggies’ solution was to build a PVAC, or Personal Vacuum Assisted Climber. It’s frankly stunning how well that thing works.
