Yes, it is true.
Yes, food colouring is a liquid.
Food colouring added to any liquid will mask the colour of the liquid, the substance contains a dye.
mix it with water
Use the paste. Food coloring liquid will thin out the dough too much.
This is not a chemical change. The food colouring forms part of the mixture on the icing sugar + flavouring + water + colouring. A chemical change requires there to be a change in the nature of the ingredients eg cooking eggs.
Food colouring changes the colour of the food.
Yes.
no it could not
Sweetheart, all countries except Siberia have food colouring.
No. the density is a characteristic of the liquid itself and not dependant on the container holding the liquid. Think of it this way: would the boiling point of a liquid change with the shape of a container? Another thought: think of a very rich, dense chocolate cake, as opposed to a very light angel food cake. You can have a very thin slice of the chocolate cake, or a ridiculously decadent slab. both pieces have the same quality of denseness, even if one is much more fun to eat.
Pink food colouring of course! and blue food colouring because there's blue cotton candy too
No. Food colouring is just a way to colour your food. It does not give off flavor.
