RIDDLES ON DLIVE -My New Program Here On Dlive

This is just for Fun:

My new program here on dlive.io called "Riddles On Dlive".

Riddles are very good for the brain for they stimulates our thinking and reasoning. And here is our first Riddle of the day- " What is that something, that when you need it you throw it out, but you keep it when you don't need it."
This is just for fun and there's no price for the right answer, so just try to answer it and tell me how many minutes or seconds were you able to answer it.

The source and the answer is here but don't open it yet, try to answer it first.

Thank you and God bless!
