Eyes not Eyes

Answer: A clock.  "Not a bird but I can fly through time": This is a metaphorical use of "fly". A clock doesn't physically move through the air, but the passage of time is often described as "flying" (as in the saying, "time flies").  "Hands moving, moments chime": A clock typically has "hands" that move to indicate the time, and some clocks "chime" to mark the hour or specific intervals. The riddle uses personification and metaphor to describe a clock's function in a creative way.

Answer: Gap.   It’s pointing to “gap” because a gap is the space between things.  In teeth: a diastema is the gap between teeth. In time: a time gap is the interval between events.  In fences: gaps are openings between slats or posts. “Wide or tiny” fits because gaps can vary in size.  So the riddle lists places where “a space between” shows up, and “gap” is the common thread.

Answer: Static. Static electricity makes hair stand on end. “Whisper between radio stations” points to the hissing noise called radio static. “Refuse to change” uses the other meaning of static: something fixed or unchanging. The riddle hinges on the word “static” having both electrical and descriptive senses.

Answer: Squeeze.  It’s a wordplay on the different meanings of “squeeze.” “Press without fingers” points to applying pressure in general (like squeezing a stress ball or a trigger). “Pull juice from fruit” is literal—squeezing an orange or lemon. “Show you love with a short embrace” nods to a quick affectionate hug often called “a squeeze.” All three clues converge on the action and noun “squeeze.”
