I enjoy all paints, but watercolor looks the coolest. What do you know about it?
I really do not know much about it. I just knot the term has been more and more passing out of use.
What about other kinds of painting?
I know a little bit of acrylic painting. 
How is that done?
Acrylic paint
Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion. Acrylic paints are water-soluble, but become water-resistant when dry. Depending on how much the paint is diluted with water, or modified with acrylic gels, mediums, or pastes, the finished acrylic painting can resemble a watercolor, a gouache or an oil painting, or have its own unique characteristics not attainable with other media.
History.
Otto Röhm invented acrylic resin, which was quickly transformed into
that particular grouping. Personally, I only know what has been said about this history; I do not know the details, nor did my comrades of the other group Metzinger, Delaunay, Le Fauconnier and Léger... But what I do know well, because I lived it and remember it perfectly, is the origin of our relations and their development to 1914, passing by the notorious Room 41 of the "Indépendants" of 1911, which provoked the 'involuntary scandal' out of which Cubism really emerged and spread in Paris
