I haven't seen anyone else mention this method, so here is what I do.
I start with the condom method..the ones without the bump.
Then put the condom bump one on the connector side, and then do like if I was packing a pack of cigs a few times, then put it between my hands and move them up and down..so the cart rolls around quickly a few times.
That's it.
To check for overfilling I gently blow out (the connector end to the lips).
