Guys please help me! I don't know what I am doing wrong. On this image I already messed up a lot, but the reason is logical. I tried to connect this two bad guys when the rocket was standing right way, but the clamp-o-trons just didn't attached to each other, I felt the magnetic force and they fit each other perfectly but no connection was established, and then i tried to crash my rocket on it's side so the top clamp became available to connect, but even in this case they didn't connect to each other when they fit. Please tell me how to fix this.
