How do you gargle?

I know this is such a stupid question, but apparently I have forgotten how to gargle.

I have had a sore throat, mucus build up, and I'm just so miserable for the past few days. I have read that gargling some warm salt water can help with the inflammation and break up the mucus.

Well I tried a few times and the water just keeps seeping down my throat causing me to gag. I dumped out the salt water and tried to "practice" with just regular water, but I couldn't figure it out. I have somehow managed to forget how to do this.

I don't even know if this can be explained 🤦‍♀️
