O-Zooka
A 2-liter soda bottle with a hole burned in it, filled with smoke, and used to make smoky rings like you're trying to look cool in front of your crush.
I used my O-Zooka in front of my crush and got a kiss, but also got detention.
I made a smoke ring so big, it looked like a dragon was flying over the school.
My O-Zooka was so cool, my mom bought me a second one for my birthday.
