Science Project “Popping in Air” Complete School Projects on Air, Water, Weather and Temperature for Class 8, 9, 10 and 12 Students.

Popping in Air

Materials Required:

  1. A single page of a newspaper

Let us make a “paper pistol.” It can be fun. The “pistol” can be made by folding a single sheet of a newspaper, as shown in the illustration.

Hold it from one corner and swing it rapidly in the air. A part of the paper comes out with a cracking noise, as if a pistol is being fired.

Fold the paper in half, along its length and breadth. Now flatten it and fold the corners on the long side, along the lengthwise fold line.

Now fold the whole paper in half to ensure that the folded corners stay inside. It ought to resemble the illustration in Figure 3.

The outer corners need to be folded towards you, so that it continues along the midline.

Now turn the packet over as in Figure 5, folding it towards you in half, along the middle. Finally, hold it at the bottom and make it go pop.

The pistol shot like sound that you hear is created by rapid flowing out of a folded part of the newspaper.

 It comes in contact with the air, as it is swung. The sound resembles that is made, when a paper bag filled with air, is crushed.
