What are the classic campus pranks?

Whole division: material: water; Our classmates are great. They are good at fooling teachers ... put a bucket in front of our door. When the teacher opens the door, it's best not to see balloons, ..................................................................................................................................., such as ketchup. You should try your best to irritate each other, and the more energetic the better. Finally, she was so angry that she couldn't help hitting you. You rushed to pretend to be injured, and then you put eye drops in your eyes and quietly put ketchup on your head. The louder the noise, the better Then more students will come to see it. Some may sue the teacher, and you will get up and wipe off the ketchup ... of course, it will be difficult to end the teacher. Material: two chairs, a wet sponge, three people, you and your partner pretend to play airplane games. One person is in the front and one person is in the back. The man in the back is the victim. When your target stands up, quickly put the sponge on his chair, and then the person in front will lower down, that is, sit down ... haha, pee your pants. Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa For example, the hat quietly hides the hat of the person you play tricks on, and then leaves a note where he puts it. You can say: Your hat is dirty. I'll put it in the washing machine. He will definitely look for the washing machine. This is you. Just put a note in the washing machine: your hat has been washed. Now he's hanging out. This is your date. It doesn't matter. Hang another note on the clothesline: Your hat is dry. Now your drawer has stopped. How boring. So you just need to leave a note in the drawer: Your drawer is too messy, I'll put it in the cupboard for you, and then leave a note in the cupboard: Your cupboard is full, I'll put it under your pillow for you. It's also convenient to hold. Finally, it is not easy for your partner to find a hat. Must be sweating like a pig, huh? Let me give you an example. I can think that the more other notes, the more fun it is until your partner runs around the room. Don't make him unhappy.
