Popping out of certain tricks


So I have been having trouble popping out of certain tricks. I have been trying to learn “iron whip”, “wrist whip”, and I am also attempting “and whut”. Each of them have a similar popping move which I cannot get down. The parts I am having trouble with is when the yoyo is sitting in one string and there is another string situated above it and the goal is to pop it out towards you. That is popping the yoyo towards you in both of the whips and it is the first pop in “and whut.” Any tips?
