ohh.... you're jiggling the lock with your pick... if you do it gently you can use a saw-tooth rake to great affect... rock it up and down gently and side-to side ever so slightly whilst trying diffeent tension whilst doing it... it can be very effective depending on the pin-combination.
single pin picking where you lift the pins up is considered to be icking but you've learnt a skill without doubt... skim through the MIT guide for details on how to single pin pick and moreso why you are able to.
as a side note I'll mention this now because someone ese will certainly... if your brother will kill you for taking apart his lock likely he'll do the same if you break it by picking it... get your own lock you can take apart.. then try to single-pin-pick... it's quite a feeling when you can do it
