How to make coffee foam?!

Best Answer - Chosen by Voters

I make my own foam for coffee with just a battery-powdered wand called an Aerolatte milk frother:

(there are other brands, and some with blade that are different but so far that one seems best) Got mine at Bed, Bath, Beyond, I think.

I use fat-free milk myself, but any kind of milk or cream can be used.
To foam well though, the milk needs to be either cold or hot (for different reasons), not room temperature.
Here's more on the Aerolatte:



And here's how I make my cappuccino-type coffee with it (pasted in from another of my answers):

I make my morning frothed coffee my own way…turns out pretty-cappucino-ish, but the proportions do have to be right.
…First, to make a strong-coffee base, I drip a heaping coffee measure of *extra fine* grind Melitta Coffee (the only type *in a can* that comes as an extra Fine Grind that I know of, and I like its flavor anyway) using a brown paper filter and plastic cone and a little less than 3/4 cup of very Hot Water (microwaved in Pyrex meas.cup), into a (temporary) Coffee Cup.
…Then I add sugar and enough 2% milk to lighten the color (3-4 T??)… I’d proabably use whole milk if I weren’t watching fat, but even 2% gives the coffee a "thickness" and good mouth feel that’s plenty good enough.
…then I put the Coffee Mix in the microwave to heat it back up (to pretty darned hot–my preference).
…Meanwhile to froth the milk, I pour about 3/4" of cold skim milk into the real cup I’ll use, then use the frother on it till it peaks on its own (…this takes only about 10 seconds when the batteries are new; when the batteries get old, it takes longer and I’ll usually stir the frother all around more vigorously to shorten the time… the batteries last a pretty long time though and for my One Cup per day, I replace them only several times a year which is approx. what the Aerolatte says it does).
…Finally, I pour the hot coffee quickly down into the frothed milk (the slower the pour, the less the froth will mix with any of the milk, so in my case some of it mixes with the milk but most stays on top). Sometimes I’ll mix more of the froth into the coffee first, but I’ve found I like the combo of the cool froth on top of the hot coffee (it warms up fairly quickly after the first few yummy sips anyway).

The foam is milk.

Thebest way is if you have a steamerr attatched to an espresso machine.

If you don't have that gently heat some milk in a pot on the stove, and whisk like crazy until it foams. Or you could heat it then put in the blender.

***The person above me is making this Way to complicated.

The foam is generally made out of milk. I looked it up for you and here's a how-to.
