Science Buddies: "Ask an Expert"

Hello,
My son is in 9th grade and he wants to do his science fair project in health related topic.
He wants to find out if corn silk tea can dissolve the human kidney stones?
Can you please help him ?
- What can be used as a subtitute of human kidney stone? And from where he can buy it easily?
- Does he need to work under professional guidance in a lab or he can do it at home?
- How can he show the dissolved kidney stone in his science fair display?

Thank you
