Basically, the idea is to use the plunger of a French press coffee maker as a platform to raise and lower your Oreo cookies into milk.
No more dropping cookies into your cup of milk and/or milk covered fingers!
Obviously, you don't need to fill the press with milk as they do in the video. Just enough to cover the cookies should be fine. They use Mini Oreos, but regular-sized ones work fine (you can always break them in half if they don't fit).
Also, you can use the same trick with Nilla wafers! ...And pretty much any other cookie you want to dip in milk.
