How to put together sand?
Answers: Hehe! well If i be you i would not reccomend Making sand unless it is just for experiment. What i would do is any buy it since it isnt that expensive, or get some from a park or sand!
But to make sand fluently, water runs down big rocks over dozens of years, and as it does this over time, the rocks variety sand. Now in directive to do it by hand i would hold to say what the other 2 family said: Grind Rocks :D
Well, to make sand yourself youl'll enjoy to wait a LONGGG time. You enjoy to wait for rock to weather and that take about 1000+ years. So i suggest buying sand from Home Depot =]
