MAKING FIMO SHAPES Fimo is like plasticine in that it can be moulded into different shapes. However when Fimo is heated is becomes hard and will retain its shape. I have used it to make grains of various shapes and sizes for experiments on grain transport in water and speed of fall of grains in water. Use different coloured Fimo for different sizes. To get several pieces all the same weight Roll out the Fimo into a sheet and try to cut out a square which weighs 1g. (or whatever weight you want).  Once you have found the correct size of square cut out more that size.  Roll each piece into a sphere.  Either keep it as a sphere or if you want a different shape squeeze it into that shape.   Heat it in an oven following the instructions of the packet
