Disadvantages
Wood is easy to get damp, swells, mold, soften, and wear and tear, and is generally used in high-end children’s clubs.
3. Sea sand

Advantages
Natural, relatively clean, and with the right particle size, not easy to cause physical damage, and the price is also reasonable. Washed sea sand is the best choice for interactive projection sand pools in children’s parks.
Disadvantages
It is difficult to clean and transport. The main production areas of washed sea sand are relatively fixed, so the freight may be more expensive than sand in some places.
4. Cassia seed

Because the particles are large and round, they will not cause direct physical damage to children’s bodies.
Disadvantages
The cost is usually 5 to 10 times that of sea sand, and it is easy to grow insects and deteriorate. In addition, Cassia seeds are divided into raw and cooked. It is strongly recommended not to use raw Cassia seeds. Although it is much cheaper, it is easy to germinate, such as drilling into children’s nostrils and ears, which is very dangerous.
