TRUMPET THUNDER - ENGLISH - 25MB.wmv

This Thundering Trumpet uses a plastic pen tube with a piece of transparency attached to one end like a flap. Place the flap in your mouth and blow out. The transparency will vibrate producing a sound. You can even suck in air from the other end to produce the sound. Attach a card sheet cone to amplify the sound.
