The 2.5 Hook is a trick that involves wrapping the string around your fingers 2.5 times.
Steps[]
It involves popping the yo-yo up and spinning the yo-yo string around the yo-yo multiple times to land the yo-yo back into a mount when it falls back down. In this case it's a 2.5 mount, which is like the one and a half mount but with two and a half strings wrapped around the yo-yo instead. So the yo-yo begins in a breakaway throw, you pop the yo-yo up, and as the yo-yo is midway through the air you take your two index fingers and wrap the string around multiple times, two and a half times to be exact, and as the yo-yo is falling back into the string you land in that 2.5 mount.
