How does the April fresh downey ball work?

Answer 1

The stopper appears to have a bottom weight which acts like a pendulem once the spin cycle begins. Normal bobbing in the wash cycle is not strong enough to start the weight "swinging" which will pop the stopper open and disperse the liquid inside once the rinse cycle begins. But the hard fast action in the spin cycle is enough to make the bottom weight swing to one side or another and pop the stopper open. I have noticed when the ball is caught inside of sheets or something big and heavy like a blanket or a couple of robes, the ball does not always open. Hope this helps
