bb tweeking again. help me

so do you think bags of rice 5 lbs or so will work like sand for dampning cd players and ect..funny thing mother in law suggested it..
I have used cat litter in the past to fill speaker stands. I find it works best in combination with lead shot.
ok guys i get you by now,i wasnt wanting this post to be funny but we had our fun,now does it matter what we put in bags?,weight is what we want right,popcorn should work.any thing we use will, right
