I was told to put Kitty Litter in my new speaker stands. Was he joking?

I built some stands in the first part of this year, as they are steel I was concerned with moisture embedding in kitty litter as it is hygroscopic. Steel and aluminum are both susceptible to corrosion/oxidation. I recall deciding that if budget is no concern, copper pellets or BBs would have been best. Steel shot that I have encountered, already has evidence of oxidation/rust so I would not introduce that into the stands. I spent an inordinate amount of time researching material and I decided on quartzite. If I recall correctly it is heavier than silica sand, it naturally breaks to a rough edge and therefor locks together really well once inside the stand columns. There is a company that produces crushed quartzite and it is labeled as Cherry Stone. I purchased a 50lb bag from Rural King for $7.99. It has worked out really well for me. The filling options are endless, sand blasting media, epoxy sealed aquarium gravel, or as mentioned above, glass beads. I would avoid kitty litter for sure.

I suggest using osmium shot or pure iridium. If not fill your stands with mercury. If you have any mercury left over mix it with equal parts vodka and lime juice and drink it while listening to the results of your labors. 

I think stuffing kitties themselves into the stands will be more effective at damping harmonic resonance but you may start getting some howling feedback...

Originally I used lead shot, is this still viable option,love AUDIO
