Explanation:

To determine the main idea, we analyze each option. Option A focuses on design aspects with physics/engineering for fun, but main idea should be broader. Option B states waterslides are popular worldwide with different twists, which is a general overview of waterslides' popularity and variety, fitting a main idea. Option C is about the physics (gravity) of how they work, a detail. Option D is about testing for safety, a specific process. So B captures the main idea of waterslides' popularity and diversity.

Answer:

B. Waterslides all over the world are popular and have different twists.
