WALMART 4-Function Whistle - Part I

Tabletop review of the nomenclature of this OZRK TRAIL 4-function [Whistle - Thermometer - Compass - Magnifying Glass] offered by WALMART.Part II will be an attempt to use the magnifying glass to initiate fire. I tried it a few days ago unsuccessfully, but the sunlight was dim due to haze and that might've been a factor.
