well the easiest one is when u put a pencil in a cup of water. Waves travel differently in different materials and refraction occurs when it bends. The pencil looks like it does not match or is not even with the part sticking out. If not you can write different names of colors. Write them in a different color than what it reads. Make someone read what the word reads. Half the brain will read the word and the other half will say the color.
