越橘草口哨

The dual magnets snap together satisfyingly, and I finally learned to whistle after years of trying. Took it on a hike last weekend and got a cheerful sound out of a single blade of grass.

My kid picked up the whistling technique in about ten minutes with this, and the dual magnets make it easy to store on the fridge between hikes.

Picked this up for a hiking trip and was surprised how solid the bamboo feels in hand. The dual magnets keep it snug on my keychain without slipping off. A bit tricky to get the hang of whistling at first, but once you do it's a fun little gadget.
