Take one large and small beverage bottle, one knife, one bamboo stick, one glass and several oranges commonly used at home. Then put the large and small plastic bottles side by side and discharge them. 12

Cut the big bottle, which is about 2 cm more than the small bottle, and then unscrew the cap. 13

Put the small bottle into the big bottle through the incision, so that it completely covers the bottle mouth. Then find the middle position of the small bottle and use a bamboo stick to pass through the two bottles, so that the small bottle can't turn. 14

Cut an orange or other fruit in half, and put two nested bottles on the cup. 15

Then put the orange on the bottom of the small bottle and squeeze it to squeeze out the juice, and the orange juice will flow into the cup. 16

Wait until the orange juice drops are clean, and then take down this small production. 17

Finally, clean the small production with water, and you can continue to use it next time, and the fruit juice can be directly quoted.
