It is pretty simple; take apart a video game controller that has rumble feature and there are the wires and when they attach they will buzz, it hurts.
You should be warned. If you do not already know how you could go about making such a device then you probably don't know how to make one safely. You could very easily go too far with a prank like this. If you are committed to doing this then you can use any kind of charged capacitor. Many of which could kill both you and your victim. Perhaps you need to get some rubber gloves. You can find a capacitor almost any electrical device. Also don't forget to put it back together, if you can?

BUZZER IS SIMPLY A RELAY THAT MECHANICALLY OPENS AND CLOSES. A speaker is a coil suspended into a magnetic flux responding to AC signals
Sure. If you want sound when the circuit is energized, use a buzzer. If you want a visual indication when the circuit is energized, use an LED.
You need a Battery, Light Bulb, Ammeter, Switch.
Its a big flexible rubber chicken.
You can get a joy buzzer at Party City or Spencers
A joy buzzer works by utilizing a small battery-powered motor inside the device that causes a vibrating sensation when activated. When someone shakes hands with the person holding the joy buzzer, it activates the motor and creates the buzzing sensation.
A buzzer is cool. You just connect the circuit.
To make a buzzer sound louder on a circuit, you can try increasing the voltage supplied to the buzzer, using a heavier duty buzzer that can handle more power, or adding a transistor amplifier to boost the signal. Be cautious not to exceed the buzzer's voltage and current ratings to avoid damaging it.
To make a buzzer with a light, you can connect a buzzer and an LED in parallel to a power source such as a battery. When the buzzer is activated, the LED will also light up, creating a visual and auditory alarm system. Be sure to use appropriate resistors to ensure the components operate within their recommended parameters.
i dont know
The buzzer will not work because there is a break in the circuit, the buzzer wont make any sound at all and it will do nothing else.

1) First, we checked if our buzzer was working. We did this by connecting the both wires from the buzzer to the sides of the battery. 2) Then we made a security alarm on the box. We placed our buzzer in the box, and made a small hole in the back, and pushed the right side wire of the buzzer through it. Then we fold a small piece of foil to the box.(over the red wire) Then we make a small hole in the foil and bring the red wire out.
Use the astable to switch a power transistor and connect the buzzer as the transistor load.
