Hi all,
yesterday I was playing with my 2 years old child in the park, and suddenly he just fell down on the grass. He put his hand in some red substance, and then put this hand in his mouth. I was very scared, and thinking that this could be blood. I went to my car, and get some hydrogen peroxide 3%. Put this on that red substance and it didn't react to hydrogen peroxide (no bubble, foaming, nothing became white).
