play dough

play dough is ... 手作り粘土。this one seems very popular in American preschools. i didn't know that and i haven't seen that until i volunteered at KidsQuest. but i have never made that one before until yesterday, for the class!
i used the recipe from website, and i didn't want to buy sth unusual, i chose one made with cornstarch. i need only flour, salt, cornstarch, and water. that's it !!
Actually, it was really hard work. i failed. i kinda gave up. i was tired. in today's class, everyone brought nice-looking colored-playdough. uh :$ but the teacher loved mine, since she needed a failed example! congrats, me... :0
