Superglue will not stick to everything. It will not stick to smooth, non-porous surfaces, such as glass, plastic, or metal. This is because these surfaces do not have any microscopic irregularities that the superglue can adhere to.
Is Super Glue Toxic Once set?
If this happens, seek medical attention. May cause skin irritation. Cyanoacrylates have been reported to cause an allergic reaction but due to rapid polymerization (solidification) at the skin surface, an allergic reaction is rare. Cured (solidified) adhesive does not present a health hazard even if bonded to the skin.

Generally, super glue is stronger than hot glue. Super glue is a type of adhesive that sets quickly and forms a strong bond between two surfaces. Hot glue is a type of adhesive that is melted and then applied to two surfaces. It sets more slowly than super glue and does not form as strong of a bond.
