1. The children had much to say that evening about Joe and the field. They had brought home a lump of chalk.
2. 'I will show you something,' said father, and he got a cup of vinegar, crushed a little of the chalk, and dropped it into the cup.
Fizz and bubble, bubble and fizz!
3. What was going on?
When the stir came to an end, the chalk was not there!
'Part of it has gone off in gas,' their father said. 'The rest is lime, and it is mixed with the vinegar.'
4. 'We did not see any gas,' said Harry.
