Summarize this article in one sentence.
You're going to create a straw with your biscuit by nibbling two diagonally opposite corners of the Tim Tam. Be sure you eat enough of the corner that you can see the creamy chocolate filling that is between the two crackers. The creamy middle is the route through which you'll be slurping your drink. If you have not eaten away enough of the malted wafer, it will be difficult for you to draw your beverage up through the Tim Tam. Now that there's an opening at opposite ends of your biscuit, you can dunk one of your nibbled off ends into beverage and begin sucking at the opposite nibbled off end. This should draw the liquid up through the Tim Tam. Your Tim Tam will also begin to absorb whatever you are drinking. Some beverages will absorb more quickly than others, but eventually your Tim Tam will become saturated. Timing is important at this point in the slam. If you wait too long, your Tim Tam might fall apart into your drink. If you jump the gun, you might find your Tim Tam hasn't reached optimal saturation. You should avoid drinking beverages that are too hot with your Tim Tam. This could result in you burning your mouth! If your drink just came out of the coffee pot, microwave, or off the stove, you may want to wait a few minutes. Once the Tim Tam has become a delicious, gooey mess of chocolate, you should quickly put it in your mouth before it falls apart and you lose it in your drink! You may want to insert your fingers into your mouth along with the biscuit so that you can lick away any residual chocolate. You should always wash your hands before eating, and especially before doing the Tim Tam slam. The melty chocolate can mix easily with dirt or bacteria on your fingers and get in your mouth.
Create the openings through which you'll slam. Suck your drink through the Tim Tam. Slam the melty treat into your mouth.
