The twins have just accepted yet another university project: this is a fairly common occurrence, right? Except for the fact that the custodian has already locked them in the laboratory to go to lunch, and Megan has forgotten the bag with all the specific items collected the day before, in the classroom.
"Does it make any difference if I say I love you very much?"
"A little, Megan, but not too much."
She lowers her head guiltily.
"It's okay, I think we'll need things that are easily available in the laboratory itself, as usual: pass me the list of essentials with instructions, at least you have that?"
She hands it to him with a slight pride, knowing that she finally did something good.
"First we need paper and plastic."
"I have a pen and a notebook in my backpack: I think we can get some from there right?"
"Good little sister, you are on your way to being forgiven."
She sticks her tongue out at him "We're twins, remember?"
"Mmmmh...then some rubber and some iron."
She visibly begins to think.
"I have some chewing gum in my backpack that should do the trick...but for the iron...well, there will be some superfluous iron that we can remove from some of the machinery around here."
"Wow big brother, thank goodness we have to do the project together, otherwise I would feel lost."
"Why do you think I insisted so much on doing it with you?"
She blushes.
"Anyway, we're twins, remember?"
"I already said that, are you copying me?"
"We also need some paint."
"Should we look around the room to see if there are any paint cans?"
"Do you think it's possible there are cans of paint in a laboratory?"
