Modeled off of the Exploritorium's resonator demonstration (https://www.exploratorium.edu/snacks/resonator), this single part print shows the resonant frequent of different length oscillators. When you shake the apparatus at just the right frequencies to match the natural frequency of the different lengths, you can drive them independently to a large amplitude oscillation.
The longer the length, the more slowly it tends to vibrate, and the lower its natural frequency. Thus, the long side will resonate at lower frequencies than the short side.
