#11 Smooth

This alien glob is a piece of gum arabic from the hardened sap of the acacia tree. most likely collected from a tree in Sudan. It is used as a thickener and emulsifier in hundreds of everyday foods like sweets and icing, as well as the glue on postage stamps, in paint and shoe polish. Its 'smoothing' characteristic is inherent in its properties on the macroscale, even this crumb, covered in bumps and lumps is beautifully smooth and lustrous. Materials have properties at different scales that echo one another, but there is no need for this to be so, and reaching the nanoscale there is nothing inherently smooth about gum arabic except its amorphous ability to take the shapes we give it. - Rox Middleton
