Dangerous Decibels Program Walk-Through: 2. What is Sound?
Troubleshooting Tips:
- Make sure the tuning fork is vibrating well and not too much time has passed before touching the ping-pong ball. It has to be done quickly before the vibrations fade away.
- Make sure the tuning fork is angled properly, so that the direction of vibration is toward the ping-pong ball. It won’t work if you touch the tips of tuning fork tines to the ping-pong ball, only the side of the tuning fork tine will work.
- Make sure the string is long enough to allow the ping-pong ball to fly away, if it is too short it won’t move as far.
- Make sure to hold everything away from the body so that clothes do not interfere
