I was messing around with Jett smokes and I found out that if the smokes are in the air for long enough, they turn into smokes (without touching anything). This is why you can't throw your smokes straight up. This tech lets you make lineups for floating smokes, which can make some insane one-ways. NO OTHER SMOKER CAN DO THIS BTW. I found one lineup here just to showcase it.
