Question: what have you made which is big

The biggest thing I have made is something to house a microscope and equipment. It was big enough to get in, like a wardrobe. But it didn’t do anything really exciting, it’s main job was to keep out all the light. It had rubber seals all around it, like your fridge at home, so when you got in and closed the door it was pitch black. It was used to image luminescent cells. That’s animals that glow in the dark. It had to be really really dark, because the light from the cells was very feint, and you can’t see them glow unless it’s really dark.
