Were humans able to boil water before we discovered how to make metal cookware? Absolutely. We’ve been boiling water in large, cup-shaped leaves for thousands of years!

We’re able to pull this off because of a process called conduction, whereby heat is conducted away from the leaf and into the water. Do you think it’s possible to accomplish the same thing with a paper cup?via(education)
Science Experiment. I try boiling water in a paper cup using a blow torch. Fun experiment to make hot water in an emergency. If you try this at home with kids do be careful and take necessary precautions. Boiling water in a paper cup isn’t as hard as it looks!
If you held the cup at an appropriate distance from the flame, the water in the paper should have eventually boiled. The circular rim on the bottom may have burned. If your paper cup had a waxy coating, the wax may have melted off. The paper cup with sand will burn slightly. The Styrofoam cup will disintegrate.
