UPDATE: Ok now this is getting weird. I just went to change some female tubs to aspen. The female tubs are different than make tubs, different rack. They are made of PE, whereas my male rack is made of PP. After giving the tub a good clean in the shower and wipe down, I put in aspen, and it flew up to the sides of the tub! I think something caused the tub to get static electricity. I would remove the aspen from the walls, put it on yhe floor, and shake the tub and the aspen would fly back on the walls like some kids science experiment! WTH?

BTW Thanks for your reply Eric
