Lazy Man’s Milk Frother
Lazy makes the world advance.
An electric milk frother you put in your milky drink (like cafe au lait), that is made out of a revolving frothing head on a pole and a top. The top covers the cup so that the drink does not come out while frothing. When turned on the frothing head starts rotation fast, and at the same time moving up and down the pole in a preprogrammed way, to get the frothing you want all the way from the too to the bottom of your drink.
