What is the mini world water curtain hole for?

Principle: Push-pull arm is used to control the drop and stop of water flow.

Materials required: push-pull arm * 1, touch-sensitive pressure plate *6, stones, power cord, 3 barrels of water.

Production steps:

1. First, put two doorposts on the square, with the width and height determined by yourself.

2. Then make a sink above the doorpost as shown in the figure below for drainage.

3. Put a horizontal push-pull arm before the doorpost goes to the sink, and the push-pull arm needs to be replaced with a wrench.

4. Dig a 2-grid deep U-shaped ditch next to the doorpost. The side is attached to the doorpost, and the distance from the front to the doorpost should be a square.

5. The U-shaped pit is covered with wires.

6. Then connect it to the push-pull arm with wires.

7. Then cover the U-shaped groove, and put six touch-sensitive pressure plates directly above the power cord.

8. As shown below, dig a deep ditch in the middle of the doorpost to connect with water.

9. put three buckets of water in the sink at the door, let the water flow into the newly dug ditch from top to bottom, and slightly block the front for decoration.

10. In this way, an automatic water curtain door is completed. When you stand on the pressure sensitive plate, the water flow will stop, and when you leave the pressure sensitive plate, the water flow will continue to fall.
