Why do heights make your feet feel strange?

When you go up high, like on a slide or a swing, your feet feel different because gravity changes how things work.

Gravity is like an invisible friend that pulls everything toward the ground. When you're on the ground, this friend is strong and clear. But when you go high, like on a tall slide or a big swing, your friend isn’t as close, it feels like they’re a little farther away.

Your body knows how far gravity is pulling from where you are. When you're up high, your brain gets confused for a second because it’s used to being closer to the ground. It sends messages to your feet saying, “Wait, are we still on Earth?” This makes your feet feel strange or wobbly, like they’re trying to figure out if they should be standing firmly or floating away.

Imagine you're wearing shoes that help you walk on the ground. If you suddenly lift one foot off the ground and hold it up high, your other foot might feel a little funny, just like when you go up high!
