Bee Hummer (Week 2: Wednesday 6th-8th)
Channel: Centro Cultural - STEAM & Robotics
Date: 2020-08-12

Let's explore sounds waves by making our own Bee Hummer. When you spin your Bee Hummer, moving air makes the rubber band vibrate. The air flowing over the rubber band makes it vibrate the same way that wind blowing over a flag makes it wave. The sound is produced vibrations, in the same way that vibrating strings on a guitar or violin produce sound. The index card helps amplify the sound, giving us this cool invention. If your Bee Hummer doesn’t seem to be working, check to be sure that the rubber band isn’t twisted, and that the string isn’t touching the rubber band, as this could cause it to stop working.
