How do you make fire with a magnifying glass?

It's quite easy- take a magnifying glass and a dry piece of a paper ( preferably newspaper ) and go to a place where appropriate sunlight is available. Let the light of sun fall on to the magnifying glass. Bring the piece of paper beneath the magnifying glass. Now your objective is to move the magnifying glass up and down in such a way that the light emerging from the magnifying glass concentrates to a point. Hold the both things in the same position for a while, and soon you will be able to see the miracle, fire without a matchstick ! Enjoy!


How do you start a fire with a magnifying glass?

well you have to get good tinder like newspaper or old branches and then pick up your magnifying lens and hold it up to the tinder. Try to get the light as small as possible. Tip/if you try to do it at dusk it wont work noon or in the afternoon is the best time.


Can you make a fire with eyeglasses?

Yes you can. You need to focus the sunlight through the lense on a dry burning material for long enough. It works the same way as a magnifying glass.


What happens when you put a piece of paper under a magnifying glass and expose it to the sun?

It all depends on how well you focus the beam of the magnifying glass. You need to adjust the distance from the glass to the paper until the light from the sun is concentrated in a tiny brilliant white spot. That spot is very hot as well as bright and so the paper is heated enough to start charring. It may even catch fire, so be careful to try this on a safe surface like concrete or stone paving. Try not to look at the bright spot with unshielded eyes, as it is bright enough to damage your eyes.


What kind of lens would let you focus the sun rays light to start a fire?

A convex lens would focus sunlight to the point that it could start a fire.

If you use a magnifying glass focus the rays of the sun could it make a fire?

Yes, if you focus the rays of the sun using a magnifying glass on a small and dry surface, such as paper or leaves, it can concentrate the light and heat enough to start a fire. This is due to the magnifying glass converging the sunlight onto a small area, increasing the intensity of the heat.


Where do you find the magnifying glass on gs mission on club penguin?

no where but if you want to make fire give the black puffle an o-berri and you have fire


How can a magnifying glass be used to make a fire?

the magnifying glass must be positioned so as to focus the light from the sun on a single point (ex. kindling), causing heat and hopefully, a small fire


What does piggy suggest they do since they can't return to the mountain to build a fire?

Piggy suggests building the fire on the beach by using the lenses of the boys' glasses to focus the sunlight and start the fire. He recommends using the lenses like a magnifying glass to create the fire. Eventually, they successfully build the fire on the beach.

Can you start a fire using a magnifying glass and a sunlamp or do you need actual sunlight?

Technically you could. The problem would be gathering enough of the light coming from the lamp. The magnifying glass fire starter works by condensing the light energy from the sun to a point. At a given energy density (depending on size of spot and lens diameter) combustible materials will ignite. The lens would need to be large enough to capture the majority of light coming from the sun/heat lamp and the focal length would be different and hard to achieve.


What are ways to start a fire in the wild?
