动画说明：
This man wanted to learn how to ride this one-wheeled electric skateboard that belonged to a friend's son. Under the kid's guidance, he initially began to balance himself on it slowly. But after only a few seconds of riding it, he lost his balance and comically tumbled off the single-wheeled electric skateboard.
