sound like a elephant
Step 1: Prepare the Can
1.wash out the soda can with soap and water
2. let it dry
Step 2: Make the Horn!!!
1. pull the tab off the soda can , then place it inside the can
2. pinch the middle of the cans until both sides meet
be careful not to slit the can edges!!!!!
Step 4: Make Some Noise!!!
apply a somewhat high pitch voice, almost like a scream and listen to the tab vibrate inside of the can this would amplify your voice making it louder.
