Anyone familiar with what "doing a push" from a crack pipe means?

Does anyone know what causes the oil from smoking crack out of a stem?

pipe is easier if u use a glass one

If u can save it ur h amazed how good the bit is for a first hit

Can you say that again? I don't think we quite got it.

I've been dabbling in crack cocaine a little more than usual lately, and I'm sure I still qualify as a n00b.

My more experienced friends have mentioned on multiple occasions about doing a "push." It involves moving the brillo around in the pipe to somehow be able to smoke the residue that has gotten stuck in the pipe.
But can anyone elaborate more for me on how to do this exactly" maybe step by step?

Also:
How often should you change out the brillo in a crack pipe?
And:
How do you know when it is time to change the brillo?
Finally:
HOW exactly do you change the brillo?

Any other tips would be appreciated!

Letting it dry and cool then taking it out fluffing it up makes a huge difference
