Handle shocker

A shocker pen is a great way to prank a friend. Imagine your friend asks you for a ballpoint pen. You give him a spare. And as soon as he presses the paste eject button, he will be hit by a small electric shock.
You can also leave the pen unattended and whoever wants to take it without asking will get theirs.

To make a shocker pen we need

Lighter with piezoelectric element.
Ball pen.
Hot glue.
Wooden stick.

Tool: pliers, stationery knife.

Making a shocker pen

So, let's disassemble the lighter and take out the piezoelectric element.

This is what it looks like. The wire is an electrode. And the second electrode is a round piece of iron on the body.

Remove some of the insulation from the wire with pliers.

We take the handle and unscrew it.

Using a hot needle, awl or paper clip, make a hole in the side of the handle.

Cut off the influx of plastic with a utility knife. Which was formed as a result of melting.

Now we need a wooden stick of a certain length. I took chopsticks from the sushi set.

We insert it into the handle. It will act as a lever that will transmit pressure from the button to the piezoelectric element.

We insert the piezoelectric element so that the bare end of the wire comes out into the hole on the side.

If the stick fits, fix it with superglue or hot glue.

Next, cut off part of the cap to hide the entire filling.

We collect the entire handle. You can put all the parts on glue.

We check and experience electric shocks on ourselves)
Be that as it may, you need to be able to play, without any fanaticism. Consider the state of the person with whom you are going to joke - what if he has a bad heart or he may not understand everything correctly and may not react adequately. In any case, all responsibility falls on you and only you.
