There is this scheme in our townYou buy a certificate containing five names for sh 500. The seller appears last on this list. You are then asked to send another sh 500 to the coordinator of the scheme and sh 1,500 to the person appearing the top of the list. Your total investment comes only shs 2,500. When these monies are paid, you get another five certificates bearing your name at number five on the list. The other people have been moved up one slot each and the person who was at the top removed. Now you sell these papers to five new recruits at sh 500 each. At that point, you recover your sh 2500 , and the numbers begin multiply . When the five certificates with your name at number five are sold, they generate 25 ( 5 x 5) more with you at position four. When these are sold, they produce another 125(25x5) with your name at number three. The next level has 625 (125 x 5) certificates “out there”. Now each of these 3,125 new members will pay you sh 1,500 making at total of sh 4,687,500!

Scenario 1: You can put pressure on a certain part of a glass frame and you will see white cracks appear. They seem to go all the way through, and yet it remains intact.

Scenario 2: Someone hits a reinforced window with a baseball bat. The cracks appear to go all the way through, and it doesn't break. Why is that?

I suspect it's to do with the molecular structure of glass.

While I'm at it, I'll just illegally bombard you with questions.
1. Exactly what is glass?
2. What makes some glass bulletproof?
3. What is it with high-pitched noises being able to shatter glass?
4. Is it possible to make a noise of such frequency that glass won't just break into smaller fragments, but actually disintegrate? The smaller the fragments, the harder they are to break, right? But could a noise be of such a pitch or force that they break into molecules so small they can't be seen?
5. And of course, my original question. How does glass crack without breaking?

They have smaller lungs and everything. I asked this question earlier, but I got two answers.
1. Are you sure they can?
2. [Link to a website about how far they can dive/how long they can hold their breath.]

According to that website, they can dive some 180 feet and hold their breaths for 18 minutes, which is the record held by the emperor penguin. Either way, I still don't know how they can do it.
