In Act One of the show, a yellow cube is lifted from a blue box, and moved across the stage.

Act Two is similar except that the yellow cube is smaller

Baby boys do not react at all to the difference and the size of the cube.

Boys enjoy playing with cubes more than girls.

As an organization of volunteers, AMSAT was putting "amateur" satellites in orbit decades before the current Cube Sat craze.

Because they're so small and light, it costs much less to get a Cube Sat into Earth's orbit than a traditional communications or GPS satellite.

The "Cube" here simply refers to the satellite's shape.

The first Cube Sat was created in the early 2000s, as a way of enabling Stanford graduate students to design, build, test and operate a spacecraft with similar capabilities to the USSR's Sputnik.

The most common CubeSat is a 10cm cube, so small that a single CubeSat could easily be mistaken for a paperweight on your desk.
