Made the first "007" dart for my James Bond pistol.
I used four shashlik pins for the shaft. Sawed off the syringe thumb rest and glued in the four wooden pins. Looks good, fits well, seems to work! Have to do some tests soon.
2 ml is a lot of liquid... proper poison that is effective at that volume would not be hard to find. I'll test it with cherry juice, of course!
