Fly a spaceship carrying a light clock (light bouncing between two mirrors) past a space station and watch time dilation happen. Compare it with a ball clock, switch to the ship’s view to measure each other’s clocks and lengths, then count muons raining down from the sky from both the ground’s and the muons’ point of view.
