Because the air pressure is 15 lb per square inch, so when you take the air out, there is no pressure inside, so the pressure outside the can crushes it.

Can sound travel through a string?
Yes. You can demonstrate this for yourself. Use a small nail or screw to make a small hole in the bottom of each of two empty tin cans. Thread a couple of inches of one end of a ten or twenty foot string into each of the tin cans, then tie a not into the ends of the string so that the ends of the string won't come back out of the tins. With a partner hold the tins so that the string is taut between you. One of you speak into his tin whilst the other listens. You should be able to hear that the voice is carried along the string.You can google for tin cans and string for pictures and more instructions.

Why two holes are made to empty an oil tin?
The tin will be turned sideways to pour the oil. One of the holes will be above the level of the oil inside the tin. This hole will allow air to flow into the tin to replace the out-flowing oil - this will maintainthe balance of the air-pressure in the tin. If there was only one hole then the oil flowing out, and the air flowing in would have to share the hole and this would lead to the pressure in the tin varying as it would reduce when oil flowed out until that oil's volume had been replaced by air. This is what leads to the inconsistent pouring of a liquid when a bottle is tilted so much that the liquid covers the opening. The flow stops and starts.
