Quicklime reacts with water in an exothermic reaction. The product is slaked lime (calcium hydroxide).

Explanation:

The equation for the reaction is

CaO(s) + H₂O(l) ⇌ Ca(OH)₂(aq); #ΔH_(rxn)# = −63.7 kJ/mol

The large amount of heat produced causes local boiling as the particles react. The steam bubbles are the water vapour that forms.
