I'm alredy using a jar of gell but I don't know what to put in it.
maybe you should look up a picture of an animal cell and look for objects that look like them and stuff it in
ex. nucleus: like a peanut or something
just a thought... well good luck!
You may use the clays that can be cooked.
You give shape to them and then place it into the oven.

These are called polymer clays.
Before i had made a DNA model using these clays.
You may find them at the arts stores and buy from each color.
Good Luck!
JUST PUT THINGS IN THAT WILL REPRESENT ORGANELLES
HERES A PIC:
