Heres a really fun gadget you can build! A Shock Flashlight!

It will give your victims a powerful but harmless shock!

With my creation of the How to build the World's Smallest Electronic Shocker, it is so small that I can fit it into a flashlight, and use it to give people fun shocking pranks!

This is going to be so fun to shock people with it, and I can guaranteed you to get laughs!!!

So lets build this fun device!

Also for the English people that may not know, a flashlight is same thing as a torch.
And please note that I am only 15 years old and I am not very good at grammar so if you find some parts of the instructable confusing, please let me know and I will try fix it.

Step 1: Get the Things!!

All right, lets get started!
You will need...

A flashlight (torch).
A very small shocker (you can build one, click here!).
Tape (I used electric tape).
Some wires.
Aluminum tape.

And the tools...

Wire strippers.
Wire cutters.
Soldering iron with solder.
Hot glue gun with glue sticks.
Drill gun with a small drill bit.

Step 2: Ready, on Your Marks, Get Set, WORK!

Now, lets get to work!

Note: The design of your flashlight may be very different from mine, but I will tell you how I did it anyway...

First, I disassemble the flashlight.

Step 3: Drilling...

I drilled two holes above the switch for the shock wires to go through.

Step 4: Install the Shocker...

Okay, I am going to put the shocker near where the light bulb is, I hot glued the shocker in place and put the -450v wire through one hole and the 0v wire in the another.
Then I attached the shocker's 0v wire to the light bulb's base, and attached the shocker's positive wire to a longer blue wire, you will see why I did this later in this instructable...

Step 5: Make the Shock Pads

Making the shock pads on the switch is a bit difficult, I cut and stripped the wire down to about 1/2 inch. Then made two strips of foil from the aluminum tape and taped it down on the switch and the wires neatly with out having the strips touching each other, if the strips do touch each other, the shock flashlight will not work...

Try make your shock pads very nicely, make it look realistic, otherwise your friend will not touch it...

Step 6: And What About the Wire?

All right! One more last thing I need to do before the shock flashlight is complete!
The shocker's blue positive wire, strip about 1/2 inch of insulation off and tape it down on the positive side of the battery, but do not tape it on top of the battery's "hump" otherwise you will prevent the light bulb to glow, tape it around the "hump"...

Okay,
If you want your shock flashlight to be very powerful (900v), put the battery with wire taped on in first, then the battery with no wire.
If you want your shock flashlight to be not so powerful (450v), put the battery with no wire in first, then the battery with wire taped on.

And then screw on the flashlight's bottom cap.

Step 7: Have Fun Doing Surprise Shock Pranks!

And you are done! You had built a Shock Flashlight!

Now go have fun by passing around the shock flashlight with your friends, they will think it is a odanery flashlight with a strange switch untill they try to turn it on... The light bulb will glow and the shocker will turn on and shock the user! Have fun with your shock flashlight and doing surprise shock pranks!!!

If you don't want to use the shocker, but the flashlight, just simply take of the shocker's blue positive wire!

Disclaimer: I am NOT responsible for any of your actions with this shocker, and what happens to people that got shocked, it is harmless to healthy people, but it may be harmful to people under age 6, or elderly, or anyone with a pacemaker, or any one who has heart problems...
And don't try give this shock flashlight to kids that is a little above age 6, you might make them cry if they get shocked.

I hoped you enjoyed this instructable!
