Vật liệu cần thiết:
– 1/4 cup of concrete (you can use water and sand to create the consistency)
– Giấy nhám
– Concrete blocks
– Drill or hammer
– thước dây

Step-by-Step Instructions:
1. Choose your material: You can either buy pre-made concrete blocks, or you can create your own by mixing cement, Nước, and sand in a bucket.
2. Measure and mark out your circular base: Use a measuring tape to measure out the circumference of the base circle you want to create. Mark out two lines that will represent the diameter of the hole. The circles should be approximately half the width of the block.
3. Pour concrete into the center of the base: Use the drill or hammer to pour the concrete into the center of the marked-out line on the base circle.
4. Remove excess concrete: Using a level, remove any excess concrete from around the edges of the hole.
5. Add the spherical top: Place the concrete block over the edge of the hole and secure it with screws or nails. Repeat this process on the other side of the hole.
6. Refill the hole: Once the top is in place, fill the rest of thehole with water and sand. Use the same measurements you used to create the base to ensure the walls are even.
7. Smooth the surface: Use a sander or pressure washer to smooth the surface of the concrete.

Mẹo:
– When pouring concrete, be sure to mix it thoroughly so that it has the right consistency.
– If you don’t have access to sand, you can use newspaper or old towels instead.
– If you want to add some color to your concrete, you can paint it with a special concrete paint or use stencils to add designs.
– Keep an eye out for leaks while filling the hole. They can cause damage if not addressed quickly.
– Once the hole is filled, let it dry completely before adding more concrete.
– For safety reasons, always wear protective gear such as gloves, kính an toàn, and a mask when working with concrete.
