Play-Doh Taste Salty

I know this is sound stupid but it really make me curious for many years since this toy appear. I always wondering how does it taste with the Play-Doh when my kids playing with it. What if they eat it or they put into they mouth! How do they prevent this thing happen to our children. To look for the solution I went to taste my daughter's Play-Doh. Lol after I just lick it and I know why kids doesn't  put it in their mouth, even they did before but will never try second time! Do you know why? Coz is taste really Salty!!!! Hahahaha I just lick softly saja and it was salty like hell macam I put one tea spoon of salt on my tongue!!!
