Looking for a powerful endothermic reaction for an experiment
have use  2 solid  Ba(OH)₂.8h2O(s)+2NH₄Cl

Hi Mr. Azar, welcome here!

The dissolution in water of many polyols absorbs heat, enough to reach -50°C for instance. Glycerine, erythritol... they get cold enough that the viscosity increases, needing efficient stirring.

Very safe (these are edible compounds), and no odour for my human nose.
