Tony was about to start telling Hope how helpful something like that would be if it was used by NASA for transporting things to Mars or other planets. And then the coffee pot went supersized and he looked like he was having an actual, factual religious experience. Complete with candles, incense, and light shining down from heaven.
Of course, he wasn't religious. At all. Unless it was at the church of coffee. Bringer of life and giver of energy.
"Wow. Can I swim in that?" Tony asked, once Hope was normal size again. He raised an eyebrow at the ant control, and almost - almost - ignored the gigantic pot of coffee in his lab. That 'almost' was because he was slowly sidestepping his way over there, while facing Hope the entire time. It looked like he wanted to bolt over there and touch it. By some miracle, he managed to refrain.
"That's impressive. The ants, I mean. Can we keep those in your lab, though? I don't need to get a massive guilt trip if you've named them and I smush an ant named Bob without thinking. Out of instinct. I just...this is..." He got close enough to reach out and touch the coffee pot. Still hot. His mind inevitably leaped from one track to another in mid-thought. "...is the chemical composition the same? Or is it altered slightly due to the particles manipulating the size of the object?"
As he looked up toward the ceiling, Tony knew the sort of military applications that Howard was probably dreaming of. There was a lot of potential for abuse there, and he could see why Pym was so protective of it. And shrinking to the point of going subatomic didn't sound fun at all. It must have taken a lot of dangerous test runs to find the right ratio from large to small, and how much was too much.
