Harmonicas
Your voice is a vibration, and you can feel it when you place a hand on your throat when you speak. As long as there are molecules around, sound will be traveling though them by smacking into each other.
That’s why if you put an alarm clock inside a glass jar and remove the air, there’s no sound from the clock. There’s nothing to transfer the vibrational energy to – nothing to smack into to transfer the sound. It’s like trying to grab hold of fog – there’s nothing to hold on to.

It’s usually because the paper didn’t lift the rubber band off the stick high enough. Try changing the spacing between the cuffs and see if this helps.
Boohoo my harmonica dosn’t work!
Mabey its because I used plain plosicle sticks.
It’s nice to make a harmonica when you don’t have a real one.
This harmonica didn’t work for me.
Whoops – I’ll have our web guy upload a new version right away. Sorry about that!
Hi Aurora,
