Let is an experiment!
We will need:
- Three identical glasses;
- A sheet of ordinary office paper, such as A4 format and a density of 80 g / m2.
The experiment goes as follows:
1. Place two glasses at a distance equal to their diameter and place a sheet of paper on them.
2. Place the third glass in the middle of the paper. Naturally, the paper will sag, and the glass will fall through.
3. Now repeat the experiment, but first, fold the sheet-like an accordion. We bent the sheet in half three times and got an accordion of seven links.
What happened? The paper withstood the weight of the glass!
But how? The sheet of paper is easily bent, but there are tough ribs to bend when you fold it like an accordion.
How much does a paper page weigh? 5 grams!
How much does glass weigh? 186 grams!
