Need help making a fake hypodermic syringe Answered

Hello. I'm set to film a scene where a needle is used to inject someone. I've found a lot of places that sell and rent fake hypodermic needles, but way over my budget. Is there anyone here who would/could be interested in making one for these? I attached a video of one being demonstrated. I'm just having a mental block on how to create one myself.

There's definitely a spring mechanism, and the tip is dulled. Other than that, I'm lost.

Did anybody ever find a proper way to accomplish this?

So I did some extensive googling and couldn't find a design for these at all. I'm shocked honestly, these fake syringes have been a standard prop for decades. It must be a trade secret. I'd really like to see some ideas for this as well.

How much do the ones you found cost? Are you handy with a dremel and epoxy?

Ok, so I couldn't stop thinking about these; I've always wondered how it was done. Anywho, this is how I would do it. The concept relies solely on finding two syringes, one small enough to fit just inside of the other. The metal tube can be found in the hardware store, and the spring inside a cigarette lighter.

I'll stop by the apothecary tomorrow and see if they'll let me peruse their hypodermic selection. I think this would work.

For sure, this is now officially on my build list. I can't believe the pre-fab ones are that expensive, that's insane! If we get these working let's go into business lol.

I did go down to the pharmacy to get syringes, but they weren't too keen on just letting me browse what they had. I'm planning on ordering some 5ml and 3ml off the internets. When I finally do get them and have a functional version I will likely just post it as an instructable.

If you finish something before me I'd be very interested in checking it out.

where were you planning on getting the metal tube?

My first stop will be a hardware or craft store to find one of those K&S precision metal displays, I'm fairly certain it will have something small enough.
If that doesn't work I'll end up turning to McMaster Carr for these 1/8" outer diameter aluminum tubes.

I'm not sure what kind of finish this metal tube should have to hide it, but right now I'm thinking that a mirror finished would be best. My theory is that it would be camouflaged by the reflection of the liquid.

Hey Tom, just seeing how your progress was coming along?

Hey there, the progress is moving, but rather slowly. I did learn that buying syringes online or from a pharmacy is a pain and they mostly come in bulk anyway. I did find a set of syringes at my parents house (they live on a farm and have some vet supplies,) but they had pictures of dogs on them -_-

My next attempt will be to print that picture out and take it with me to a vet supply store so I can explain what I'm trying to do. Maybe it is just the town I live in, but people get suspicious when I try to tell them what I want, and I think the plans would show that I'm not just making the story up.

Have you found anything of use?

I was just going to suggest a Veterinarian's office, Tom. It's perfectly legal to purchase needles and syringes... and they probably won't even ask questions.

Hey Tom, thanks for replying.

So far I've found these can cost from $200-500. I'm pretty handy, as long as I have directions, or some kind of tutorial. Thank you for finding that.
