- Long white sparks fly from the piece held against the grinder wheel.
- The middle piece throws short red sparks.
- The right-hand piece rests flat on the bench.

- A bar magnet lies beside the scale.
Examples
- A drinks can and a steel food tin look alike, but a magnet picks out the steel.
- Scrap yards grind a piece of metal and watch the sparks to sort mixed metals.
Key takeaways
- Different metals have different densities and throw different spark colours.
- Sorting by alloy before recycling keeps the recycled metal clean and useful.
