Please explain, how to make a ping pong ball picker

1. First, we can use scissors to cut off the upper part of the beverage bottle, cut off the bottom of the mineral water bottle, and cut the bottle wall into 3 cm strips at the bottom of the bottle, and then Cut a hole under the mouth of the mineral water bottle through which a table tennis ball can roll out. This hole is used to make it easier for us to get the ball;

2. Then use scissors to cut off the bottom of the drink bottle. During this process, be careful not to cut in large quantities to avoid making mistakes and not being able to save them;

3. At this time, you can try to adjust the inward part of the outer wall on the edge of the fracture, and adjust it outward a little bit. Too much force;

4. Then use an awl to poke four symmetrical holes at the bottom. The spacing should be slightly smaller than the diameter of a table tennis ball, about 35-40 mm;

< p>5. Pass the two rubber bands through the two symmetrical holes respectively, tighten them and tie them at both ends. The ropes on both sides should be the same length, not one long and one short;

6. The distance between the rubber bands cannot be larger than 4/5 of the table tennis ball, otherwise the table tennis ball will be easily adjusted out.

7. Then tie the old broomstick to the side of the beverage bottle with wool, making sure it is tied firmly.

8. Then a simple table tennis ball picker is made. The method of use is very simple, just point the pole at the table tennis ball on the ground and press it up.

9. At this time, the table tennis ball will not fall out because the distance between the rubber bands is smaller than its diameter.

10. Finally, we can use the ball picker to collect the table tennis balls on the ground, and then turn them upside down and put them in the container. Be careful not to collect too many table tennis balls at once, so as not to break the string. Break.
