All you need is a candle, something to scrape the wax off the candle, a piece of paper and some matches! Erosion is demonstrated as the wax is scraped off the candle, transportation by the pieces falling down on to the paper and deposition by the build up of pieces on the paper. It's then easy to continue to demonstrate compaction, metamorphism, melting and 'crystallisation'. However, which processes are NOT demonstrated? (Weathering, cementation, rising, extrusion, uplift).
