In this module we will explore different types of solids and discuss how their structures relate to their behavior. Differences arise from the different properties of the two crystals, including the atoms that compose them and the actual structure of the crystal itself. For example, you can pass an electrical current through salt water and light a light bulb (you might have done this experiment yourself) but you can’t do this with sugar water. Nonetheless, they have very different flavors, and they behave differently too. These pranks work well because salt and sugar are almost indistinguishable by the naked eye: Both are crystalline solids with similar structures.
Or go the other direction and you can really disrupt someone’s morning when they take the first salty sip of coffee. It’s a classic prank: Fill a saltshaker with sugar and wait for the meal to take an unexpected turn as your dining companions wonder why their chicken is oddly sweet.
