tom swift among the diamond makers

 I had a mid-test in the book it not really that hard it's like an easier question. but like you know some times you get not as much interesting and you have no idea what you are talking about. I think I am going back to find out what an isotope is I thought they sued them in microscopes. I have like no idea so I am going to find out other than that I knew most of the questions besides the other page the newer. you get the easier it is unless it's super interesting than you remember. like in the labret tar pits I knew most of the questions from there because that is very interesting.
