I've been in a research lab all summer doing a sort of internship program. Anyway, my research adviser has really spent a lot of time with me helping me get things done in the lab as well as taking the time to make sure I understood the science behind what we are doing. I want to get a little parting gift for him to thank him for all he has done for me. I was just wondering if anyone had ideas for this type of thing. My default is usually gift card but I'm not sure if that would be appropriate. So, any cool chemistry related gifts would be great, or just ideas in general for this type of thing.
