blood banks charles drew

Easy project ideas?! PLEASE HELP!!?
ok so first of all if you clicked this than THANK YOU!!
yea so i needed to take a shoe box.. and make something on the inside that has to do with charles r. drew (he invented the blood bank) .. there has to be a movable part.. i really need answers now cuz this is due on monday and i only did the outside of the box..so what can i do on the inside?? (im in 6th grade so nothing REALLY hard..)
k thanks!!
who cares if im supposed to be on here or not…
Alright..one the inside, have people (obviously not complex people) , like one or two. And then have them lying on those beds that people lay on when they get theyre blood taken, and then have the things that the bag with the blood is taken in (with the hangy thingy) and then for the moveable part, have blood being drawn in the baggy. Like make it big enough that you can like put paper on the inside of one them and then when you pull the paper 9or something attached to the paper), the “blood” is being drawn into the bag.
hahaha..yah I don’t know any medical terms, and hoopefully that explains it enough that you get what i’m trying to say lol
answers mine?
