You are making a type of pastry used for choclate eclairs, profiteroles, croquembouche or Paris Brest. It must bake quickly in the oven, puffing up so that it is filled with air, but with the pastry setting crisp and firm so that it retains its shape when you take it from the oven. A strong flour has more gluten (the protein in wheat). Protein hardens when it is heated. If the choux is to be filled with custard or cream, for example, it is important that it is strong and dry so it doesn't turn wet and flabby. When you take choux buns from the oven pierce them immediately with a sharp knife or cut a small cross in the bottom before placing them on a rack to cool. This allows the steam to escape and also creates a hole through which to place the nozzle of the piping bag when you fill them. They can be quite brittle so you want to reduce the handling as far as possible. Don't fill them until the last possible moment before they are served.
Mercury is not used in piping.
Pâté a choux
There are many uses for pastry bags. They're most often used for piping decorations on assorted desserts, filling (chocolate etc) cups or (pie) shells, writing on cakes etc. Some are disposable, and some are re-useable and washable. You can use metal tips with them for different designs as well.
Marzipan is not considered a pastry. Marzipan is a confection made of ground almonds or almond paste, egg whites, and sugar, often molded into decorative shapes. It can also be used to cover a cake as icing and can also be a filling for chocolates.
Puff pastry involves layering butter into a shortcrust pastry, then completing a process of folding and rolling and folding again, in order to obtain many thin layers of butter spread within thin layers of pastry. When the pastry cooks, the fat in the butter keeps the layers separate, while the water content expands into steam and forces the layer apart. In a rough puff pastry, chunks of butter in mixed onto the pastry as it is made, and the pastry mix needs only be rolled once. with the lumps of butter within the pastry, the same effect happens, but over a small localised areas. The effect is the same, but the rough puff doesn't rise quite as much, and finishes with a rough texture. It is, of course, much quicker to make. Use it when the pastry will not be on show, such as for the base of tarts and the like.

The pastry bag, also known as the piping bag, was invented by the famous pastry chef Marie Antoine Careme (not to be confused with Marie Antoinette). He pioneered many things while cooking for famous people such as royalty, one of which was the modern signature trait of any chef today; the chef's hat, aka the toque (before it was used to refer to knit caps, otherwise known as beanies).
