Defense system against burglars and other bad people

Living in a city apartment, the question always arises of how to protect it from uninvited guests, such as all sorts of thieves and other bad people. Many put alarms and armored doors, bars on the windows, but even such measures are sometimes not able to calm zealous crackers.

Any drunken rowdy who has arranged such a feast on your landing may also disturb you, and there’s no one to disperse this rabble, it’s dangerous to go out by itself, it’s often a long time to wait for the police.
We have to look for a rational way out of this problem.

And here is what the author of the invention offers to scare away unwanted guests. The method is very simple and ingenious, the master assembled a remote gas installation based on a cylinder with tear gas "bird cherry" and several other components that will be discussed later. What should go directly to the device itself, but first you should familiarize yourself with a short list of materials and tools necessary for manufacturing homemade.

Materials
1) tear gas cylinder
2) chinese sticks
3) electrical tape
4) a dropper tube 1.5 m
5) syringe 2 pcs
6) liquid

Instruments
1) stationery knife

Surprisingly, everything is just the role of the remote switch will play two syringes communicating with each other, they are filled with liquid. When you press one of the syringes, the liquid is supplied to the second and pushes the cuffs with the bar up, thereby pressing the button of the cylinder and further spraying.

The author has prepared the components.
Further, the master assembled everything in a single design as described above.
Installation tests are in progress.Then the actual installation takes place, one part of the tube with the syringe remains in the apartment, with which it will start.
The second part is mounted near the front door from the outside, carefully disguised as something, for example, in a box with wires.
When you press the syringe, the liquid under pressure will push the cuff of the second syringe, and that in turn will press the button of the cylinder and tear gas will spray on the landing.And all the brawlers will scatter like cockroaches from your porch, it is unlikely then they will want to bother you with their presence)))

But of course it’s better that nothing happens, so that you don’t have to put the mechanism into action!
