Treat your feet to a short “beach holiday” and let them sink deeply into the sand. Attentively sense the temperature of the sand and the sand grains on your skin. Can you feel the granularity of the sand or does the sand surround your feet more evenly, like soil would do?

Again, your feet touch the sand and the sand touches your feet. Bring your attention first to one direction (your feet touch the sand) and then to the other (the sand touches your feet). Then see if you can sense both at the same time.

If you want to do this in a public sand pit, please make sure nothing potentially harmful is hidden in the sand.
