Each grain represents a galaxy.
In the midst of all the sand sits a magnifying glass.

The Big Playground - Sand as galaxies
If a grain of sand represented an entire galaxy, you would need seven rooms full of sand to contain all the galaxies in the universe. I have taken a single grain of sand, which represents our Milky Way galaxy, and drilled a hole 1/10th the size of the grain of sand into it. This hole represents where we have already found over 120 planets. The grain is seen under a magnifying glass.

A space where people could play in this enormous amount of sand and imagine running their fingers through millions of galaxies will be memorable. Each grain of sand, or galaxy, contains 100's of billions of stars. To see the insignificant area we have looked for earth-like planets is powerful.
