FIREWORKS - simple idea for KS1

Here is a fantastic poem written recently during one of my workshops in Key Stage One:

Writing a firework poem is very simple, and can be achieved in the following three steps. 

(1) write down five different colours

(2) develop these into similes

(3) intersperse each line with some onomatopeia (e.g. 'whoooosh!')

Why not give it a go?
