  1. Of note is that those ‘compressed air’ cans also contain some pretty nasty stuff as propellants. (If you’re warning about the PVC dust we should probably be thorough.) Not necessarily the sort of thing one would wish to vent into their home on a regular basis. (Not that i don’t use the stuff myself for cleaning electronics).

    Or just use lungs/bellows/piston/etc.

  2. Made this with my kid and it’s friggin awesome. Only issue is the suction isn’t that great. Any way to improve that? Did I do something wrong???
