Intro: SOUND ENERGY GENERATOR
A sound energy generator produces sound that can affect some things. Its because sound is a form of energy and can make things move or shake. This sound is like air bursting out off the hole of this contraption, this 'air' travels on a straight line for lust a few distances (the bigger the generator, the farther the air travels)
Step 1: MATERIALS
The materials.... You need a cardboard cylinder with lid (like a can of potato chips or some thing like that), plastic or cloth, tape, and cardboard (optional). You also need scissors.
Step 2: CUTTING TIME
cut out the bottom part or the base of the cylinder...
Step 3: PUNCH a HOLE
punch a small hole at the middle part of the lid. don't make a large hole because it can ruin its performance...
Step 4: COVERING a LARGER HOLE
cover the opening at the other side of the cylinder with the cloth or the plastic then tape them together...
Step 5: TEST IT
try blowing the fire out of the candle by aiming the hole to the fire then tap the other side of the contraption and try going nearer to the fire until the fire is out.
Step 6: ENLARGE IT
make a larger version using larger things like a big drum and try blowing out a bonfire!
