Firstly you will need to buy a revolver metal cap gun
Next you will need to remove the orange tip (do this with tweezers or and other thing thats easy to use)
Don't break the gun
Next  if the chamber where you load the cap comes out can come out take it out (Don't worry if it can't)
then look at the opposit end to where the caps go in  there should be some hole lining up with the caps
This is where your bullits will go
You need to measure the diameter of the hole. imagine it was 6mm
Then go to your nearest hardware store and buy a meter of circular 6 mm wood or metal
then cut in up into 1cm pieces you should have 100
Next if you want you could sharpen the end to a point
But insert the bullit into the hole at the opposite end to the caps
then place the caps on the end
Now comes the exciting part!
Fire the loaded cap gun
Did it work?
if not don't worry go and get some flammable spay like deoderant then spray some on the cap to give it more ompffh
then take it out side and remote fire it by threading string on the trigger where you hand would beand pull on the string
It should have worked that time if not keep putting deoderant on untill it works
Good look
P.S Do not try this if you do i Cannot be held resposible for injury do this at your own risk
