I was wondering about the nasal spray ballast tank. I drew this out i dont know how exactly it would work. Im still working on the valve part and pump any ideas? Dang it!! it wont accept it. I drew it on microsoft paint. My cam has too big of pics. SO i cant draw it out by hand either. Well if you really want to see any pics i guess i could send it as an e-mail. That is for if i have any pics that i really have to show.
