Paper Tent

WHY?

When you blew under the tent it didn't move the paper tent. This is because the faster the air moves the less pressure it has. So when you blew air through the tent there was less air pressure under the tent than on top of the tent. The heavy air on top pressed down on the tent. That is why, when you blew very hard, the tent was 'sucked' to the table. When you blew against the side of the paper tent you blew it off the table. An airplane stays in the air for the same reason. The top of the wing is curved. Air travels over the wing and moves faster than the air below the wing. The faster air above the wing has less pressure now, and the slower moving air below the wing has more pressure. The heavy air below pushes the wing up.
