The clean whistle / The clean whistle

The clean whistle

The usual whistle may touch clothes when we hang it on our neck, and it would touch our mouths when we use it, this is an unhygienic way and may spread bacteria. We add a simple shell to whistles, which can push the whistle out of the shell when we use it. When it is not being used, the whistle would go back to the shell because of gravity, so it can solve the problem.
