It may be a little late for your son's homework but... one of my friend's father was involved in the preparations for Dahl's funeral and included with his remains were some of the things he loved to use. This included his favourite pencils (he always wrote in pencil), some Cadbury's chocolate (apropros considering his most famous book), a full bottle of red, an electric saw complete with cable and plug, and his set of snooker cues. Quite a fitting, eccentric, and wonderful assortment! His hip bone was not buried with him.
