You are tapped on the shoulder from behind, and when you spin around, you see the shining face of your favorite teacher, Professor Sato! She was a pretty attractive Japanese woman in her early thirties, with short brown hair. She was pretty skinny, and always wore these thick black glasses, but she was undoubtedly cute. You always felt like she was flirting with you, but never really acted on it. I mean, c'mon, she's your teacher! But nevertheless, Sato looks at you and says "So, what's up?" You ask to go into her office and the two of you go in, her locking the door behind you. You take a seat at her desk and she says "So, what was so important you couldn't say it out in the open?" Without saying a word you reach into your bag and pull out the gun. You are about to ask what she knows about it, but Sato grabs it from your hands and smiles saying "Oh my god... you found it!" Ah. So she does know about it. She inspects the gun making sure it's not damaged or anything and sighs in relief saying "Thank you, thank you, THANK YOU so much for bringing this back to me! Someone took this from the lab a few days ago, and i've been wracking my brain trying to get it back! I've spent my entire grant for this year on this device, it's been my livelihood to create it!" You pretend not to know anything about it and hope she'll give you all the info you need. "So... what does it do? Is it like a weapon or something?" She looks down at it smiling and says "Well, i guess SOME people may consider it a weapon. It's part of a program i've started called Project Gulliver. Basically it's designed to increase or decrease the mass of an object to whatever size you wish. It could be a solution to several problems from world hunger to overpopulation... and now I have it back! Thank you, thank you THANK YOU!" You ask kind of coyly "Well... does it work on people?" She raises an eyebrow and says "I don't know, it hasn't been tested thoroughly yet, so i don't know how it would react to human tissue... but I guess if you'd be willing to do some tests with me today..." You smile and say, trying to be cool, "Well, I don't think i have a lot going on today. Sure, i'll give you a hand." She bites her lip ands says "This is going to be great! Something tells me you'll be the perfect assistant for this job." She gets up from her desk and gives you a big hug in gratitude. "If we're going to do this, it has to be absolutely confidential, nobody can know about it but you and me." You look at her and nod in agreement. She smiles and says "Okay then..."
