finger tricks breaking my cube?

[MYKE]

when i'm doing a solve faster than i normally do, i use my index finger(s) to move the U face and my ring finger to move the D face.

when i do this i'm pushing the corner cubies and i think i'm slowly seperating them and now it makes a rattling noise if it's shook because of the loose corners.

is this ok? am i slowly breaking it?
MYKE...

yea this is called "cutting corners", like R follwed by U' by pushing the cerner thru! your cube will be moe and more flexible when you use it (loosening tension on the screws and SLOWLY recess off inner surface)
