i made this play-doh kinda thing last friday. it was really interesting how some flour, salt, water, oil, and heat could combine and form such a fun substance. the food coloring is optional, but it does make it whole lot better! to make this, you:

1. put 1 cup of water, 1 cup of flour, 1/2 cup of salt, 1 tablespoon, and some food coloring (optional) of oil in a bowl.
   
2. stir the ingredients over a low heat.
3. watch and stir about 5 minutes, so the liquid will thicken and turn into dough.
   
4. leave it in the bowl until it is cool enough to touch.
5. put it in a plastic bag to keep the dough from drying.
6. HAVE FUN!
   

Science
when you leave play-doh out outside overnight, it dries because the water in the dough evaporates. the water is responsible for the play-doh's pliability. making play-doh is also a reaction. it goes from liquidy to stretchy with the help of heat!
