We’re setup in the Boulder County Fair Grounds exhibit building. Come see us and say hello!
As always, the Cyclophone is a popular crowd pleaser. Here member Rob B. demonstrates it to some faire participants.
Our cymatics displays were popular. However, further investigation needs to be done on driving the surface transducer that powers the plate: we burnt it out today. 🙁 Below is a picture of our cymatics replacement, oobleck. However, we burnt out the speaker in this experiment too. 🙁 :(. Twice in one day. Ouch!
Here I’m pouring the cornstarch and water mix into the bowl that’s glued to the face of the speaker. Unfortunately, it just didn’t get up and dance like other examples. More experimenting to come!
