It actually depends on what you're trying to burn a hole through. It can from a thin piece of paper to a large block of wood.
I have only tried it for paper, and this is what I did:
You make a spot on the piece of paper where you want it to burn. Try using a black sharpie because it attracts more heat. Take a typical magnifying lens and hold it between the sun and paper. There should be a weird shape, or dash of sunlight on your mark of sunlight. Make sure the light is refracted right, and is not spread out, but more focused to one point.
It all depends on the weather or season really. During the summer, you can go outside and try it, and it will happen pretty fast. For the winter (which I tried), I was inside, in front of a mirror. I had to wait patiently for a few minutes, and the sun was moving by the hour, so I had to make sure my angle was correct.
Hope this helps :D

Can you get a 3rd degree burn from the sun?
No, unless you are 'trying' to. The sun usually leaves first degree, but if you use a magnifying glass, it can.
In what year did Roger Bacon invent the magnifying glass?
Roger Bacon invented the Magnifying Glass in the year 1250
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!

Why do ants burn under a magnifying glass?
When you place a magnifying glass over an ant and the sun is out, the light from the sun hits the convex glass and becomes concentrated at a certain point. That point will eventually become hot enough to burn the ant.
Why couldn't the US get a big magnifying glass or something like that to keep the temperature warmer in the winter?
A big magnifying glass will burn the US, one neighborhood at a time.
Why do objects burn when light shines through a magnifying glass?
well usually you need something stronger then a magnifying glass, but it increases the heat from the sun and burns something in its radius
How does a plant burn when a magnifying glass and the sun join?
If you mean to ask how a magnifying glass can use sunlight to burn a plant, then here's how.A magnifying glass focuses the light going through it so that it all converges into a single point (focal point). The light that would have otherwise been spread out over the area of the magnifying glass is "concentrated". Therefore there is much more energy hitting that one point than otherwise would be. The light raises the temperature of the plant to the point where it will burn.
How long does it take to burn a paper using magnifying glass?
It depends on the color, so i can't answer that.
Why does a magnifying glass must be held so that the light from the sun forms a circular dot to burn paper?
A magnifying glass forms a circular dot where it focuses rays of light from the sun. The focus of a magnifying glass is at a distance from the surface of the glass itself. So a magnifying glass must be held [approximately] perpendicular to the line joining the sun and the target, and at a distance from the target which equals the focal length of the lens.
How do you make a worm blow up?
Magnifying glass or cook it maybe, or just try to burn it in someway.
How are magnifying lenses constructed?
Have you ever wondered how a magnifying glass is constructed? A magnifying glass is constructed by using a convex lens to curve and magnify objects. A magnifying glass is also constructed out of glass.
Could you burn an ant with a magnifying glass?
Yes. When the sun hits the convex glass, the rays are concentrated into one point. that point heats so fast that anything the beam hits, it'll burn.
Can you get a 3rd degree burn from the sun?
No, unless you are 'trying' to. The sun usually leaves first degree, but if you use a magnifying glass, it can.
