How many folding chairs do you think you could eat if metal didn't fuck up your body?
Assuming the chairs are, say, about eight pounds (which seems reasonable) and made of aluminum (that’s 2.7g/cm3), that’s approximately 1.3L/chair if you were to, like, mince it into a space-efficient form. So, like, between one and three at the upper limit depending on appetite? That’s between “regular meal” and “the absolute limit of human stomach capacity” for the limits btw.
