Absolutely, I was a little over-zealous with my first coolerdor. I added an extra foam seal and put in a pound of beads (this one's pretty big though). I quickly learned to let the beads nearly dry completely before re-wetting. Then, only wet them until half are clear and half are white. Just don't add too much water at one time. It's best to re-wet the beads over a 2 or 3 day period.
I learned the hard way, I was exploding good sticks by keeping the RH too high. When you get it right, they are the best IMO.
