Name 3 scientific equipment that you think the professor used in the novel. Describe them in detail.

There is the time machine itself. Other than the novel's description I can't think of more to add, I'd only be using my imagination.

time machine is the first scientific equipment used by the professor, but what about the other 2? there are 3 equipments in totality. tell about the other 2 also. (if you can)

This question is asking for your ideas rather than a specific answer. Take some of the ideas above and consider how you might alter things. Give it a try!
