you guys only put 5 sheets in???
when i made em i PACKED the tube full. tight enough to where you couldnt blow the sheets out the other end. no tape.
my mom was a freak, she had a nose like a dog. maybe she was just guessing and was always right! lol. but it worked with her 4:5 times.
used the same tube and sheets for quite a while, kept it in a baggie day to day.
