Nice Idea Answered

This is NOT my idea. I do not take any credit for it in any way.

I just found this on You tube. I thought it was a brilliantly original idea, and wanted to show everyone here that there really is no limits to knex. 


Very cool idea i might make it!

COOL what is it though?

Rock tumbler to polish rocks/stones, I didn't make it, its just an idea.
