Some people enjoy dressing up for halloween and often use fake blood. Making up some fake blood is quite simple. All you need is some glycerine (available from chemist shops or the supermarket) and red food colouring. Mix well together and store in a well labelled bottle. Fake blood can also be made by colouring some syrup or honey with red food colouring. When using food colouring (or poster paints which do the same thing) please remember that the colouring stains so do not get it on clothing! Always add food colouring one drop at a time as the dyes used are very intense.
