Question by hope: How is an easy way to make a solar water heater?
I have to somehow boil a bottle of water in less than 50 minutes. Any ideas would be great!

You use a parabolic mirror or get something shaped like a satellite dish with lots of tiny mirrors on it. You put the bottle in the focal point and it will boil very quickly. (about 2 mins)
example below:

Make a parabolic dish with a diameter of about four feet and line the inside surface with aluminium foil and focus its reflection on a glass bottle that is full of water (not a plastic bottle) and DO NOT put a cap on the bottle. The output of such a dish is more than enough to fry eggs in a couple of minutes, so it should be enough to boil a pint of water in less than 50 minutes.
You could also make a heater from about fifty feet of 1/2 inch diameter black PVC hose but this would be more difficult and less safe to make for a school project.
