Itch Scratching Project

[deleted-485644]

Hey there,
I have a science project coming up soon at my school and my idea is to make an object that could get scratch an itch without hurting a skin by abrasion. I was wondering if anybody had any ideas on what materials to use that is skin friendly and doesn't cause too much friction.

Hi 241237cc20fa4c0fbfd3ce33073cfc89,

A quick online search for “back scratchers” revealed lots of possibilities. One example is described here:

There are numerous sponges, pumice stones and other gently abrasive materials used to remove dry or dead skin. An example is shown here:

I hope this helps. Please post again if you have more questions.
