Light goes in a straight line.

It doesn't twist or wiggle.

Flashlights shine light straight.

Light can bounce off shiny things — that's called reflection.

Mirrors show reflection really well.

Light can also bend in water or glass — that's refraction.

In air or space, light keeps going straight.

We see things because light comes to our eyes.

Lasers shoot straight light too.

Light moves super fast and straight!
