I just built a fluid bed based on various things I have read here. I haven't seen any of the tutorials that people have been PM'ing around.

I have used 2" PVC and I have a smaller air pump for it. The problem I am having is the air seems to be coming up through the powder in small tunnels creating craters on the top and making the powder come out of the cup. It's not an explosive type cloud coming out, but more of a mist.

I do have a valve inline with the air pump and it doesn't help when I lower the air flow, it just makes the powder all settle down. If anyone has any ideas on how I can get a better, more even air flow through the cup to fluidize the powder I would appreciate it. I am using a brown paper bag for the cup bottom.

Thanks,
Corey
