Most of you have probably tried that astronaut ice cream they sell in science museums. It’s pretty nasty. I think the folks at NASA are trying to make up for that atrocity because they’re currently working on a 3D printed pizza that you can actually eat.
The idea is that you’ll have cartridges full of the ingredients like cheese and sauce which will then be layered and mixed to make your pizza. Apparently the layered nature of pizza makes it a natural for the process. That, or the guys at NASA are just really tired of having to tip the pizza delivery guy while they work on important science stuff into the wee hours of the night.
