Discussion
A series of familiar objects are shown with their mirror reflections. The mirror is removed and the mirror images tested for superimposability. Chiral objects have nonsuperimposable mirror images and form a pair of enantiomers. Achiral objects have mirror images that are identical (superimposable). The following objects were tested: snail shell (chiral), pencil (achiral), glove (chiral), hand (chiral), a carbon atom with four different substituents (chiral), a carbon atom with three different substituents (achiral).
