I found a cheap source for sniffer bottles

Its in the paint department (well in that area I they might have been in the spray brush area) of Hobby lobby, they call them spray bottles ranging form .55 to .99 cents if I remember correctly. I bought one of all then took them home. Now find some soda straws and push them in the nosel (this is before cutting it) next mark the area a hairs breath farther up then where the straw touches it all the way around. Then mark it and cut a little farther up so if its too tight you can trim it down. Then all that is left is to cut the angle in the straw and push it threw, the hole in the nosel should be just smaller then the straw to ensure a tight fit. Now you have your cheap sniffer bottle in assorted sizes.
