Is hot glue strong enough?
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.

Gorilla glue is very strong, but takes longer to set up and will stain your fingers black. It all depends. Hot glue would be easier to use as the clamping requirements are minimal. Gorilla Glue, on the other hand, would probably form a stronger bond between the sticks, but clamping would be a big headache.
