Stefan Help?

OK, so I know that I have to get FBR for the body, but I am unsure what to use for the weight. I saw one video where the guy made the heads from hot glue in a playdo mould, then melted a bit to make them stick in the body of the dart. Most other sources say to use split shot fishing weights, or metal washers. I am concerned also about the safety factor as I have a 9yr old sister who is... Let's just say... Fragile. Mum would kill me if the darts left welts and/or bruises.
So... what can I use and how do I get performance without sacrificing safety?

EDIT:
Custom NERF Darts - "Stefans"

This is the method I will most likely be using to make my Stefans. I didn't want to use any kind of metal weight or anything too painful, so I settled for hot glue (which is still better than the original streamlines). 

Materials:
-FBR: Foam Backer Rod, available from hardware stores, must be in 1/2 inch. 
-Hot glue: colored is optional, but looks cool. 

Method:
1. Cut FBR to desired length - official darts are 6.4cm long, use this as a guide. 
2. Place all the cut blanks in a pillowcase and put into a dryer for approx. 10mins on medium. When finished, the blanks should be straight. 
3. Take one blank and, with a hot glue gun, melt a hole in the centre of the top of the dart.  
4. Fill the hole with hot glue, and make a small dome of glue on the top.
5. Repeat steps 3-4 as necessary. 

Is there anything wrong with this way of making them? Is there anything I should be doing differently?

I found that when I started nerfing this was the most confusing topic, so I'll help you out a little.

Inf0rm3r sells everything you'll need, blue foam which works in all guns stock or modified, snap caps and silicone tips which are used as the heads and PETG, the barrel you'll need. To add to that you can also use 16mm electrical conduit from electrical stores. Both head types are very safe, one being safer, easier but more expensive the other being a cheaper, close second.

Get some snap caps or preferrably sili tips from Informers sales thread.

I don't think you should be shooting around your sister with stefans requardless of their design.
If you going to be shooting around her, maybe only streamlines from a lightly modded reverse plunger blaster.

Thanks heaps guys, but I think I'm gonna have to have a crack at making them from scratch myself, being the tinker I am.

It was mostly just because I didn't want to lose the ability to shoot close range, without hurting anyone, that is.
Looks like I'll be keeping the stefans in the dart box whilst I war with my sister anyway - I have heaps of streamlines to use.

Clunkedit.

Hey whebzy try to avoid double posting instead use the 'edit' button on your last post

Also when you get a chance please update your age, location and upload in an avatar.

G'day buddy Everything that your are doing is right. But I have a suggestion instead of melting a hole in the top. Hot-glue a 3/16 zinc washer to the top and then glue a felt tip on. These are dead accurate if made right and they don't hurt. (The washers can be found at home hardware.)

@Shrapnel - Please update your avatar, age and location as tgis to forum rules. Also, please introduce yourself in the introductory section.

Moved to the question's thread.

With the small snap cap darts are the 25cent ones just the head or dart sorry I am new to nerf.

If this is informer?
If so, their 20c each.
If you want to make your own, I can surply you with the snap caps.
If you come to the war on saturday, you can grab some off me.

Where can you buy a felt tip of that size? Thanks.

You can make your own, or get them from some crafts stores.

Alright, thanks. Just thinking of some alternatives to sili tips and snap caps. They are still the best though, haha.
