How can I determine if the sand I'm using is of good quality?

You can look for information about the sand's origin and its composition. If you are unsure, you can also ask a local beach or playground operator for advice on what type of sand they recommend. Additionally, you can test the sand by pouring it into a container with water and seeing how quickly it settles. A fast-settling sand indicates that it has high-quality particles and should be suitable for play.
