Which is scarier, the U-shaped skateboard or the big pendulum?

Big pendulum. According to relevant public information, the feeling of playing with a big pendulum is the most horrible. When the whole person flies several times, people will feel shivering, weightlessness and sweating. U-shaped skateboard is the perfect combination of high jumpers and roller coasters. It stands in the sky like a huge horseshoe-shaped magnet, attracting infinite energy between heaven and earth.
