Here they are:
1. "Believe as many as six impossible things before breakfast." This is the line that introduces the list.
2. "That milk could be made to come out of a cow with a twist of the wrist."
3. "That a pig could fly."
4. "That a tree could grow out of a hat."
5. "That a fish could live in the air, and that the sky could be reached by digging down."
6. "That a rhinoceros could win a race."
It's important to note that these are not truly impossible things, just things that would be considered unlikely or strange. Carroll uses this list to highlight the absurdity and logic-defying nature of Wonderland.
