An ingredient can also be a material! Just add a few drops of ink to flour to create modelling clay! If the ink accidentally gets on your clothes, some lemon juice is all that's needed to remove any stains!
I have organised two "Alchemist Matter" workshops for children during the "Reciprocity" Design Triennial in Liège. These practical activities, based on the use of a kit, give an understanding of the usefulness of science, by introducing your children to chemistry through creative and progressive learning.
