Water in a bowl or a paper cup can be boiled over and open flame, neither the bowl nor the cup would burn because the heat from the flame is absorbed by the water and the water, at sea level, can't get hotter than 100 C, this is not hot enough to ignite paper or wood.

You can put the bowl in an air tight chamber and attach a vacuum pump to the chamber. As the air is removed and the pressure inside drops to somewhere around 29 inches of mercury the water will start to boil at room temperature. The water vapor (steam) will be drawn off by the vacuum pump until all of the water has been boiled off. Once there is no more water the vacuum pump (if it is powerful enough) will then be able to further pull additional vacuum and reach 30 inches of mercury....

Several options:
1)Use a microwave oven.
2) Keep the bowl in a chamber and use a vacuum pump to evacuate the air above the water bowl.
3) Use a lens to focus sunlight on to the water surface.
4) Use an electrical immersion heater suspended in the bowl without touching the sides.

No matter where you boil water start with cold water. That’s right, cold water, not hot, even though that would heat up faster. The reason is this: when hot tap water sits around in your pipes, the higher temps allow the gunk that's collected in the pipes to dissolve more readily in your water. And you don’t want to be ingesting that, right? Anyway I think if you're in your own home, the microwave would be your best bet!

You can boil water in an oven, in a microwave oven, on an electric skillet, on an electric plate, in an electric tea kettle, in an electric coffee maker, in a kiln, under a heat lamp, on a heating pad, in a toaster, on top of your car hood while and after you drive, etc.
Also, if you in a really hot place at a high enough altitude, you don't even have to get the water to 100°C and it'll boil.

Actually, you csn boil water in a paper bag over an open fire, because the water absorbs the heat before the bag gets hot enough to burn.
You could try using a solar reflector. Camping shops sell them.

Fire. Buy an MRE kit from a military surplus store. In it will be this lil baggie. When it is mixed with water, it will heat up REAL hot.

increase the temperature and decrease the volume in the container that holds the water. this would increase the pressure which would produce heat. but you would have to wait an excruciating amount of time!! MUAHAHAHA you will dehydrate before you get your boiled water, suckaaa

Use a stove rather than the stove.
Or perhaps...
A very large magnifying glass and the sun's rays.
