As I've pointed out in my last post, I too have struggled with this question regarding Chi's interaction with matter, and while thinking all the arguments over in this thread here yesterday, it finally occurred to me why it may be that it's easy to throw around some people while it may not be so easy to move some wooden blocks or apply a force to a measuring instrument. Since Chi is traditionally regarded as a "life energy" by the traditions that study and cultivate it, then it seems logical that Chi would be present in human bodies, but one would expect wooden blocks to be rather deficient in life energy (since they're not alive). If we think about this in terms of magnets, if you take one magnet and move it near another magnet, we can expect the second magnet to be attracted to or repelled from the other. However if you took the magnet and tried to do the same exact thing with a wooden block, there would be no motion at all. Now we wouldn't conclude that there's no such thing as magnetism based on that experiment, just that it has limited interaction with the world. In the same way, Chi has limited interaction with the world, so one would expect limited interaction with the non-living and much stronger interaction with living matter that itself contains other Chi. As I suggested, perhaps your experiment shouldn't be in regards to measuring a force from a non-living instrument, but rather to move a rat or something with very low human suggestability to minimize chances of the master issuing commands.
