How do I reel him in??

Guys, what kind of hints can I drop to let a guy know I'm interested in him, (besides smiling at him)? Just wondering because I'm trying to grab the attention of my crush a little more instead of using just subtle hints. Like I think I'm getting his attention...but I think maybe I need to spice it up a bit && stop being so "safe". Today he sat in a desk behind me && when I asked him if I could share his textbook with him, he said yeah. I made some small tlk as we were doing our assignment && laughed @ the jokes he && his friends said. He smiles when smile. && I noticed his eyes seemed brighter or glassy-looking when he looked up @ me to smile, once today. Is that a good sign that he's interested, btw?
