And they are great on a rainy day. You just take the nuudles and put the end on a damp cloth or sponge and they become sticky. Yes, you are not going to want these thing around forever but They are hours of fun at our souse. Today we made a barn and farm animals and after they are made Harrison plays and plays and plays with them. This box is about $6 so they are not super cheap BUT some days it SO WORTH IT :) We are on our second box and Harrison has played with them for over 10 hours so that's not too bad.
