Pathfinder Challenge Day 4- Part 2

Challenge: Using natural materials only, made a whistle to use as an audable signal


Usually the simplest solution is the best, and this is the perfect example. I could spend my time and energy carving a very intricate whistle or I could simple tension a blade of glass between two thumbs with my hands put together and get a very effective audio signal.

you decide.
