How can I animate phase of a particle

Hello, I am trying to make dandelion seeds with a particle system. I want to spin them around themself.
However, when I keyframe the phase and hit play I see no difference during the animation.

Is there something I miss?

thx a lot for any help

Here you find the blend file attached dandelionseed.blend (845.6 KB)

Wish i could answer your question, but cant. Maybe moving this over to the Support forum rather then the Artwork forum will help. Good luck.
