Peter quickly decided he liked Otto. He seemed like a fun guy to be around, and he was funny. Peter returned Otto's grin with one of his own as he walked in. "Save the hero worship for mr Stark." He looked back at Tony with a mischievous glint in his eyes and an innocent smile on his face. "It's a good thing he didn't see what you were doing before we came down here, right mr Stark?" No one would believe that the great Tony Stark had not only just been in a tickle fight, but that he had actually started it. Peter felt giddy at that thought. He was seeing all these sides of Tony that no one else did - or besides the Avengers, Happy, and Pepper, at least. He pushed it from his mind and turned back to all the interesting things in the room. He walked further into the room as he looked at the projects in the room. "Oh, I'm looking for some materials to make a more durable, lighter, stronger, and smaller turbine." He tore his gaze away from the interesting things to look back at Otto. "What would you recommend? I'd also love to know how you made these!"
