1. Measure the height of the slideway and record it.

2. Mark the beginning and end of the slide.

3. Record the sliding time with a stopwatch.

4. Repeat many experiments to get more accurate data.

The characteristics of various slides are: plastic children's slide, glass fiber reinforced plastic slide, steel children's slide, engineering plastic children's combined slide and wooden slide.

1, plastic children's slide

Colorful colors, novel and fashionable design, plastic children's slide has always been called the champion of children's slide sales.

2. FRP slideway

It is made of glass fiber reinforced plastic, also called glass fiber reinforced plastic. It is a fiber-reinforced composite plastic and a tough material. It has the characteristics of light weight, high strength, corrosion resistance, antistatic and ultraviolet protection, and is durable, safe and reliable.

3. Steel children's slide

Steel children's slides are generally built on slopes, which have the advantages of good strength and firmness, and are more common in residential areas or parks. Steel children's slides are more challenging in gameplay and design difficulty, and more fashionable in appearance.

4. Engineering plastic children's combined slide

It is the most widely used one at present. It is permeated with anti-ultraviolet agent, antistatic agent and anti-decoloring agent. High strength, smooth surface, safety, environmental protection and good weather resistance. 10 years will not fade. Imported PPE engineering plastics, once molded by advanced rotational molding technology, are brightly colored and do not fade, and are deeply loved by people.

5. Wooden slide

Imported Fraxinus mandshurica wood is hard, good in drying performance, strong in water resistance, not easy to wear, crack and deform, and straight in texture.
