Bjaardker,
I put the bowling ball and the Optisorb in a plastic bag which I tied tightly. I then rotated the package so that the Optisorb was distributed rather evenly around the ball. Then I let it rest for 48 hours.
I had not understood that the Hook Again granulate might be drier. I still have the Optisorb in the same plastic bag. Perhaps the Optisorb now has dried enough to have an effect? if not, would shredded paper be a good antidessicant to add?
Regards,
