Glass table = hum? Why?

When I set my microphone stand on a table I get a hum. How can I fix that without spending a lot of money or holding the microphone the whole time?

This is a follow up to this question:
After hours and hours of troubleshooting I have discovered the source of the hum--my table. I don't know WHY, and as mentioned in that previous question, this is somewhat new behavior as I recorded like this for years without any hum.
But with my microphone stands sitting on the table, I get a hum. If I lift the stands into the air, there is no hum.
My setup is that I have two microphone stands, metal with rubber feet, standing about 8" high. At the top is your standard plastic mic clip. In the mic clip is my mic. Also attached to the Mic stand is a pop filter.
I set these on my desk, an office desk with a glass top.
I am guessing the noise to be vibration related, but I have turned off all other electronic devices on the table and still get the hum. Further, I have tried "buffering" the mic and the table with bubble wrap, carpet, and paper, and all three still produce the hum.
I have looked into tripod stands for the floor, but due to the set-up, to keep those out of the way would require a 4' or longer boom arm, and the one I tried had balance issues with the boom extended all the way out.
I'd prefer to not have to spend over $200 on mic stands to fix this problem, but not sure how else to fix it. Any ideas would be greatly, greatly appreciated.
