I thought this bath mat was the most interesting one I had ever seen! It is made out of live moss! That sounds half enjoyable and half really messy, but it appears to work really well in the pictures. I really would like to try it out because I have so many unanswered questions! How does it feel on your feet? Do you need to water it? Does the moss die if soap gets on it? Do your feet get dirtier by stepping on the mat? If not, how does the moss survive without dirt? This has me so intrigued, I guess I will have to do my research!!
