Fix one end of the string on South America and bring it across the Atlantic Ocean to Portugal, then down round the bottom of Africa and across the Indian Ocean to India's west coast. When you have finished you will see that the chilli travelled more than half way round the world.
How to trace it, step by step:
- Take a bright red piece of wool, about 60 cm long — red, so that it is easy to tell apart from the bird's string.
- Find South America on the globe. Fix one end there.
- Carry the string north-east across the Atlantic Ocean to Portugal, on the western edge of Europe. This is where the travellers who carried the chilli came from.
- Now bring it south along the west coast of Africa, right round the southern tip of Africa.
- Turn north-east across the Indian Ocean and fix the other end on India's west coast.
- Stand back and look at how much water the string crossed and how little land.
| Stage of the journey | What it tells you |
|---|---|
| South America → Portugal | The chilli first went to Europe. It did not come straight to India |
| Portugal → round Africa | There was no short cut then. Ships had to sail all the way round the southern tip of Africa |
| Across the Indian Ocean → India's west coast | Ships arrived on the west coast, which is why chilli spread inland from there |
| The whole route | Almost entirely over water, and it took months. This was 400 to 500 years ago, in sailing ships |
