This is how a K cups work.
When putting the K-cup into a coffee brewer, it will punch a hole through the top and the bottom of K-cup. Then the machine will force hot water going through the K-cup and ground coffee can be absorbed into the water and this hot water will extract soluble substances of the powder including coffee taste and aroma. This brewed coffee runs out of the bottom of K-cup and pours into a coffee mug underneath.
The whole process is automatic, which is very fast in speed and convenient. A K-cup can hold coffee flavors in each of its cup. And they also are able to filter your coffee. The only thing you need to do is loading up water and place a K-cup into the machine brewer, and then push the start button on the top of the machine to start brewing your coffee. A metallic tube in the machine will poke a hole into the K-cup to let pressurized water run through coffee ground in the cup. When the machine determines your coffee is done, it will poke another hole at the bottom of K-cup to let coffee liquid run out.
