This is a strictly for fun and comical video tutorial that teaches you how to make a musical instrument specifically a "kazoo" with a gas mask. A kazoo is a wind instrument which adds a buzzing sound to a player's voice. This makes a creepy sound effect to a mask. You simply remove specific parts of the mask to turn it into a kazoo. The video also has a great finale where the performers use the kazoo masks to sing the acapella version of "The Lion Sleeps Tonight".
