Why dosen't superglue stick to the tube?
لماذا لا يلتصق غراء السوبر جلو بالأنبوية نفسها؟

ANSWER
"Super glue" is cyano-acrylate, CH2=CH-CO2-CN, a low molecular weight, low viscosity liquid. It has no adhesive properties. Upon exposure to the atmosphere it polymerizes rapidly to form a high molecular matrix. It is the
polymer that gives the adhesive properties.
