In gravity -9.82 its super simple to make a cork
but in gravity -30.00 its harder to make a better and realistic cork
Jisse has good corks and here is one of them

Is this what you mean by a cork?

Evdromeda, no, that is an Arabian (backflip 180). A corkscrew is a one footed backflip with a 360 twist, where the practitioner swings their outside leg in order to gain momentum to form the flip and twist.

ok, I have had some misinterpretations on what a cork is, thank you for clearing that up for me
