Photoluminescent sand preferably includes play sand, photoluminescent pigment, a powdered binder and a curing agent. The play sand is preferably mixed with the photoluminescent pigment to form a photo sand mix. The photo sand mix is then mixed with the powered binder and curing agent to form the photoluminescent sand mix. The photoluminescent sand mix is allowed to cure for between 3-7 days to form the photoluminescent sand.
