and Never Drying If you click through to their recipes you will see that they both differ slightly and even they don’t all agree on the liquid ingredients So we set out to figure out the best Moon Sand Recipe! WHAT EXPERIMENT DID WE DO WITH MOON SAND?
Jun 03, 2019· What Is Kinetic Sand? Kinetic sand is largely regular or play sand (about 98 percent), mixed with a polymer, which is a long, repeating chain of molecules that gives the sand its stretchy propertySince it has the consistency of a very dense fluid, people enjoy messing around with kinetic sand, as it will always return to its natural stateUnlike standard sand, kinetic sand doesn't dry out or .
