4 and 5 tone-hole Blastoids

thingiverse

These were experiments used when coming up with the 10 tone hole whistle that I entered into the "Make It Loud" challenge: http://www.thingiverse.com/thing:1161114 Even though the Decatone Blaster is my official submission, the ones in this posting are probably the ones you'd rather print as they do not require so much breath to activate. Here's how they work: Place flat on table Fully plug ears with pinkie fingers BLOW!! Here's the vid of the Quadtone on youtube (and I'm not using ear protection.... sheesh): https://youtu.be/osQZ2n5PLKs The shinier image above is the Five Tone Blastoid after acetone vapor treatment. It actually works better than when it first came out of the printer. Enjoy!
