Made this today with my 6yr old niece. It does not come out as smooth as it does in the video. It is gritty. Our first attempt ended with my niece giving up and saying " you do it" as she left the room. I pushed all of it into the trash. Where she says "one cup of mixture(flour&salt)" PLEASE notice she spoons it into the cup and does not fill it so its probably more like a 1/2 cup scooped and leveled or 3/4 cup spooned. For my second attempt I just put mound of mixture on table and added liquid in center like I was making pasta. If to dry I added more, if to wet I added more of the mixture. Also when she said "warm" water...I found REALLY warm water worked best. Eventually I made 4 different color balls for my niece and there was still enough mixture left for another 2-3 colors. Still a bit gritty once mixted well but a lot cheaper then store bought. Seeing how my niece loves to mix the colors thus ruining them in my opinion. Just have to keep old Play doh containers for this stuff, and I'm all set.
