5 Minute Syringe Pen




Follow me on Youtube

This instructable will show you how to make a syringe pen in 5 minutes or less. The idea of making this just popped up into my head when I saw this syringe which was lying around in my house for a while (of course clean and without a needle). Please clean out the injections before using them for this instructable. These syringes were for pet use. Enjoy the instructable.

Step 1: You Will Need

For this instructable you will need
1. scissors
2. epoxy
3. a small stick
4.a pencil
5.a syringe washed with soap and anti bacterial
6. a cheap pen which is easy to take apart
you usually get them in hotels and stuff.

Step 2: Take the Pen Apart

To get to the pen mine you will have to take your pen apart by either pulling the two ends
away from each other or if you have a different type you can just screw it apart. You will not need anything from the pen for this project except for the pen mine.

Step 3: Cut the Pen Mine

The next step is to cut the mine closest to the ink. Dont cut it too close or the ink will spill.

Step 4: Push the Pen Mine In

The next step will be to push the pen mine into the syringe as far as you can with the stick. Then lay the thing you push into it beside it and cut it to the length you want it to stick out the end.

Step 5: Glue It In

The next step will be to squeeze out a bit of epoxy and mix it hard. When you are done with mixing put a bit on the thing you push in. Dont use too much glue! or it will run down and it wont give the effect.

Step 6: Final Product

    I know i have to be missing something here, but i notice in the pics the ink is still in the pen mine. Having binged the walking dead recently, (the movie shooter comes to mind as well) could this be used on humans in an emergency situation? My questions are what happens with the ink? I know ink cant just be injected lol. Also given length of the tip as well as sharpness, could this even reach a vein? Id imagine in a prison scenario theyve fashioned these things from less, it really is astonishing what the human mind,can create when backed into a corner with all that idle time to think.

    Out of interest, does gluing the end of the biro stop it working after a while? I think I did something like this in the past (I wanted to make a mini pen to carry around when I was at primary school - as adult pens don't fit in kid's pockets)... I think it's probably to do with the ink still needing some atmospheric pressure to feed the ink out.

    If I'm wrong, cool. If not perhaps putting a small hole further down the ink tube will equalise the pressure? Anyway - love the I'ble. Will have a go for sure! Great idea =)

    I found out leaving the pen mine a bit longer and then making a small hole in the side
    works great. But also when the epoxy is nearly dry just pull the thing you pull up a bit so there is a small gap between the pen mine and the glue.

    This is awesome!! I agree with Cheeseduck it would be an awesome click pen!

    This is really cool! It's probably possible to make it a click pen, but this way is so simple.
