How does a downy fabric softener ball function even in a cold water wash?

When the washer goes into its first spin cycle, cetrifugal force pulls the ball sideways, with the bottom on the side of the washer and the top pointing towards the center. The spin cycle is fast enough that it pulls the rubber stopper at the top of the ball back in. Then, during the rinse cycle, it fills with water, which releases the softener.How does a downy fabric softener ball function even in a cold water wash?
it is the action of the spin cycle that opens the ball not the water temp.How does a downy fabric softener ball function even in a cold water wash?
It's all about the agitation. Prior to the rinse cycle, the washing machine agitates the load this causes the ball top to pop open and then as water fills for the rinse cycle it mixes with the softener. :) At least that's what I think happens. LOL
It does'nt matter what temp it is hot or cold it opens up in the spin cycle I love those things that way you dont have to wash for the spin cycle you just throw it in and thats that
The ball works in any temp water because it works during the spin cycle and it doesnt really have anything to do with teh temp of the water. I am not sure exactly how it works, but i think that it has something to do with the weight that is on the little plunger thing that is underneath the rubber seal that closes the ball. When the washer starts the spin cycle, that weight gets pulled into the ball by the centrivical (or however you spell it) force and pulls the seal open and all of the downy comes out.
