Heating Water without electricity
Hey guys, im doing an assignment, and the aim is to get water heated as much as possible without electricity.
We don't get to use mirrors or magnifying glasses.
We get to use 1.5m of aluminium foil, black cups and cardboard. No lighters, or any other heat producing equipment
Any ideas as to how i can do this?
Thanks

Drink and then piss it out.
It will be salty but w/e
well aluminum foil will refract light
cardboard is a good insulator (because it gives lost of space between the inside and outside, and air is the best insulator)
and the color black absorbs light best.
these are the facts i know. good luck.
fire?
Swim in the water. Your kinetic energy will increase the temperature.
use a lighter? that doesn't use electricity and it can act as a heating source for the water. It'll warm the foil which will transfer heat to the black cups.
so layer the cardboard first, then cover the base of that cardboard with foil underneath and have the cup sit ontop of the cardboard on the top. then use the lighter to heat the base.
