📋 What it is
Illusions connect physics (light), biology (the eye) and psychology (the brain) — a three-part team can be fooled.
🗣️ Coach says
Every illusion is a three-part story. PHYSICS decides what light does; BIOLOGY is how your eye captures it; PSYCHOLOGY is how your brain interprets it — and the brain fills gaps and makes guesses. Illusions fool one of these three links. Knowing which link is tricked explains why the illusion works.
🧠 Memory hook
Illusion = physics (light) + biology (eye) + psychology (brain guessing). Fool one link → an illusion.
😂 Giggle
Why did the prism break up with the flashlight?
It said, "You're showing your true colors!"
😲 Whoa!
Your brain does most of "seeing" — your eyes send it a blurry, upside-down, gap-filled signal, and your brain builds the clear, steady world you experience.
✅ Quick check: What three things does every illusion involve?
Say your answer out loud first — then reveal.
Physics (light), biology (the eye), and psychology (the brain interpreting) — an illusion fools one of them.
Illusions exploit the light-eye-brain chain.

For one illusion, ask: is the trick in the LIGHT, the EYE, or the BRAIN? Usually the brain.
