RED slime! It was quite a lot of fun. the slime behaves rather strange - it is solid when you grab a handful and roll it up like playdough, but when you let it rest it turns into liquid and drips down your fingers. Try it!
a cup of cornflour
water (room temp)
some food coloring *optional
-gradually mix water into the cornflour until you get the consistency you like. food coloring too. mix it all slowly. mix it hard and fast. Play.
