Hi, this is my first post. I joined this forum specifically to ask for help with the following.

I'm trying to find small instruments that can be taken along while camping.

I don't really care how exotic the instrument is, as long as it meets the following criteria.

-Must be smaller and weigh less than a set of standard playing cards.
-Must have very few or no moving parts.
-Must be able to play several notes.
-Needs no batteries or electricity.

Instruments I'm considering:
-Harmonica
-Jaw Harp (aka Jews Harp, Mouth Harp)
-Kazoo
-Kou Xiang (aka Kouxian)
-Nose Flute (aka Nose Whistle, Humanitone)
-Pendant Ocarina
-Pan Flute: Some can be as small as a pack of cards
-Slide Whistle
-Thumb Piano (aka Kalimba, Mbira): Some can be as small as a pack of cards
-Tin Whistle

Can you add to this list?

I would really like to find an instrument that sounds like a guitar, yet still fits the criteria above.

Or can you suggest instruments that can be made from simple items while camping.

Examples:
-Drum = pot, pan, water bottle, hollow log, etc.
-Recorder = hollow stick with finger holes
-Xylophone = several sticks or rocks lined up and struck with a stick to create tones.
