Here you can see her demonstrating her "mad skills". I like when, at the end of the video, Dad asks her "what her feet are doing" and she stops spinning so that she can lift her feet and show them to him.
Tovina was a little scared by the device at first. Then, once she got past her unreasonable, albiet healthy, fear of the somewhat unstable, noisy when moved, oddly shaped device, she spent the first few hours thinking it was a stand-n-spin. However she eventually got the idea and became a champion Sit-N-Spin rider. Just look at the sense of accomplishment you can see in her eyes.
