Burning up the Paper with a Magnifying Glass

 Instruction 

Step 1/2 – Wear sunglasses.

 Troubleshooting 

Why I can not find the focal point?
— You need to adjust the distance between the paper and magnifying glass.

Why I can not burn my paper?
— Maybe the sunshine is too weak. You want to use tissue paper or some dark paper. The darker the better.

 Question to Ask 

Can I use the ordinary glass, instead of a magnifying glass?

 Scientific Description 

A magnifying glass is a double convex lens that focuses the light rays striking the surface onto a single point (focal point). as we all know that the sunshine has energy. When the sunshine focuses on a sport, the light decreases in size but intensifies in brightness. Concentrate that much energy on a single spot so that there is enough energy to burn up the paper.

 Extensions 

You can try if you can focus the lamplight to burn the paper.
