Cirio on 24 June 2011
Hmm, maybe I'm not understanding this right, but what is the benefit from mixing rice with the sand? Is there a special property in rice that causes the toxic molecules to be attracted to it? If so, what is this property. Because if the regular filter paper isn't sufficient enough since it can't trap the smaller toxic molecules, couldn't they simply make the "gaps" in the filter paper smaller by filling the gaps with the carbon oxide mentioned above? I'm a noob when it comes to rice chemistry lol.
