here is a tek for making a syringe. it's the first i found but i've read a method i think would work better.
sterilize everything, fill a syringe with distilled water and wrap it in foil. pressure cook. in a sterile environment scrape some spores into a pre-sterilized shot glass, inject a little water into the shot, mix the spores and suck it back up. voila, a spore syringe.
