So, I cracked my chewin' molar yesterday, so it's currently in three pieces. Even swallowing the wrong way brings a fresh wave of agony, but I got my dentist appointment set-up. ON THE 21ST.
EDIT: Oh, I also found out that it was NOT a good idea to make another cannon with a larger bottle, and thus more aerosol. Long story short: Small explosion in my backyard. Luckily, we bailed to my friend's house for movie night before any cops may have showed up. I doubt any did.
