An amazing experiment with air

WOW! this is awesome is what you are going to say after reading this post ) 

If u have a syringe with a cap on it in your house, try this out ; let the syringe's cap be loose and just push the plunger with full force, you will see that the cap flies fast and the damage can be powerful, this proves that air occupies space and hey you have made your own air pistol!

Note: Even if you shoot, it wont hurt anyone , its just the sound
