lol, when you first look you think Rice Sand? what is this, Mixing Rice with Sand?, but it has nothing to do with rice its called Rice sand because the university is called RICE and thats there sand lol.

I have no clue what you just said.

Rice isn't used in the mixture. The name of the University where the student "invented" the sand is Rice University, hence the adoption of the name "Rice Sand". The sand itself is a mixture of copper oxide with the filter paper; no rice is involved.
