One of my favourite aspects of doing art & science projects in high school in Chennai, India was that I got to stick my fingers into tubs of Fevicol, a white glue adhesive. The delicious part was not so much sticking your fingers into the tub but waiting for the Fevicol to dry, and then peeling it off your fingers. White cobwebs with your finger prints on them. Fevicol was the first ‘real’ easy-to-use and readily available glue of its kind in India – you could use it to hold together all manners of materials and surfaces.
