I've been wanting to make this project for some time and I have finallly been able to get my hands on the right type of gas lighter to pull apart!
Now this thing won't knock you down but It will give you a good old shock - especially if you hack it and add a bit more power to it.
This is a really easy project which anyone with a little soldering skills can make. All you really need is a "continuous piezo electric sparker" which takes a battery. These are used to light gas BBQ's, heaters, etc and can be purchased from Amazon or Ebay. (see link in step 1)
Remember to be careful - it is electricity afterall and I don't won't anyone to hurt themselves!
Saying that, there is nothing bettter than to zap your brother on the arse and watch him jump!

Step 1: Step 1 Parts and Tools
You will need the following parts to make your Mini Stun Gun
1) Piezo Electric Spark Starter. These can be purchased from Amazon
2) AAA battery holder - it needs to hold 2 batteries
3) Thick electrical wire, as well as some normal, everyday electrical wire.
4) Wire (this is to make the prongs at the end)
I used the following tools but just use whatever you have that will do the job
3) Soldering iron
4) Stanley knife
5) Hot glue gun
6) Phillips Head Screwdriver
7) Heat Shrink Plastic
Step 2: Step 2 - Pulling the Piezo Sparker Lighter apart
Carefully take out the insides - the wires from the battery terminals to the circuit board are quite weak, these came off on mine after some time so you might need to add a bit more solder to these.
