The laser sound is similar to the 'pew pew' laser noise made in old space films. This is a versatile sound that can be executed in various ways and can be done in conjunction with the chest bass to create a sonic boom sound or a throat bass as well.

How it's done

1. Pull your bottom lip over your bottom teeth
2. Place the tip of your tongue against the back of the bottom row of your teeth
3. Create the initial whistling noise by blowing air out with the air really focused on flowing through your tongue
4. Now prolong that whistle while moving your bottom lip in and out over your bottom teeth.
