I love little facts about common things and so I found this good one today and thought I’d share:
Rice Krispies, also known as “Rice Bubbles” in some countries, are created by preparing rice in such a way that it will “pop” like popcorn during the cooking process, albeit much less dramatically. This popping puffs up the kernels. When the rice is finished cooking, most of the Rice Krispies will have thin, solid walls with hollow, sealed areas inside where air pockets have formed. When cold milk is added, the sudden temperature shift causes the walls of these air pocket regions of the Rice Krispies to fracture suddenly, making a snap/crackle/pop type noise!
