Crunching leaves on Shabbos

Question:

BH
A student of mine likes to step on leaves as she walks, because she likes the sound of the crunch. She wants to know if this is permissible on Shabbos?
Thank you

Answer:

Hello,

Yes, it is permitted to do with your foot, but not with your hands, (as they are muktza). It is not considered tochain, since the person doesn't necessarily crumble the leaves, additionally the person does not want to break the leaf into small pieces, rather only to get a noise out of it, by cracking it.

Best wishes
