I'm in my school's rocket club and we're launching in November. Along with our actually serious rocket, I wanna make a funny "joke" rocket because why not.

Please suggest any funny filaments you know of (within reason, I'm not buying a £600 roll of nylon infused with goat's tears), I'll pick the best one and report back in a month or so with a rocket. The dodgier the better (I have a P1S with a hardened steel nozzle so should be ok with most stuff).

Only limits are no ABS or ASA as I don't have the facilities to deal with the fumes.

Thank you in advance!
