There are dolls and cars and blocks, and there are lenses, mirrors and prisms. We played with both.
Summer afternoons were sometimes spent burning carbon paper with lenses, making rainbows with prisms, or simply spinning the colour wheel to see a muddy grey mix of colours (instead of the theoretical white). We would be fascinated by how things appeared upside down when seen through lenses, and how they would distort in convex and concave mirrors. Sometimes we would just lie back and look inside a kaleidoscope, and sometimes we would try to look at the moon with binoculars.
While my interest in science took a deep dive in high school once it became all about formulas and calculations, optics remained the only subject I managed to enjoy in Physics.Even now, I occasionally gaze into this dusty old kaleidoscope I bought a few years ago.
Even now I run outside every time I see a rainbow, staring at it till it fades into the sky.
I try to zoom into the moon more and more with every new camera phone.
And I still get lost in the colours of light scattered by glass.
