野比家が無重力

On the first page, there is no words in the speech bubbles but images, which makes this manga that much more precious.
Nobita is hanging in his room in the air by a rope holding him up by the waist. He is swinging around happily until Doraemon comes in first surprised, then starts cracking up. In his speech bubble is a turtle hanging in the air held by a string wrapped around its belly. Nobita gets angry and kicks Doraemon to the ground while in the air. He explains this in his speech bubble which is of an astronaut in space.

Nobita: I'm not playing. I am practicing for zero-gravity situation. What for? In the future, I want to become a space pirate. My goal is to be the first to land on Mars.
Doraemon: Didn't the US and the USSR already do that?
Nobita: If not Mars, then Mercury. If not that, 木金土日...anything is good so that I can be the first to land and leave my name in the history books!!
(*Mars is 火＋星、Mercury is 水＋星, therefore all the elements+星。。。）
Doreamon (thinking to himself): Suddenly, a dream-like idea comes to mind. カーツとwill get dizzy but it's for Nobita's sake.
(talking to Nobita and digging into his pocket): Then, this would be good. Whether you can or cannot do it is the difference and I approve of your future dream. (Takes out a scale) "The Gravity Regulation Machine". You can make from zero-gravity to twice that of earth's as much as you please. Let's lower the gravity in this room. This is .5 G. So everything in the room should be half of its normal weight.
Nobita (lifting up his desk): It's true! My body has become light, I can jump twice as high.
Doraemon (changing the machine): This is .3 G. This is how it would feel to land on Mars.
(Nobita hits his head on the ceiling because he jumped to high)
Doraemon: Watch out. 0 G! Finally, it will become zero-gravity!!
(Everything flies into the air)
Nobita: There's no controller to use. (Nobita is having a hard time controlling his body in the air)
Doraemon: Put this on your finger. Push the button (on the controller). (Nobita moving with the controller on his finger)
Nobita: It's like a rocket.
Doraemon: You're going to hit a window. Point your finger in another direction. (Nobita avoids the window) When you're uncomfortable, point your finger back down. You have the freedom to fly.
(Nobita does a backflip in the air)
Doraemon: Nice, nice.
Nobita: Switching up and down is fun.
Doraemon: Well, I have to leave for a bit but don't do anything stupid in a zero-gravity house. (Doraemon leaves into the desk drawer)
Nobita: That's right. This whole house is zero-gravity. (Plays with machine) Just make my body the lightest and increase the space of the house. (Nobita is flying room to room smiling and laughing). It's like going to the astroid belt in space. (Flies out into the yard). The garden's also zero gravity. Oh, there's Shizu-chan. Hey! Here, here! (pauses) I'm out of the zero-gravity bounds. (Nobita falls from the skies to the ground infront of where Shizu-chan is walking) Good afternoon. (pushes Shizu-chan into his house) Come on. It'll be interesting.

(Both starts to fly while entering the house)
Nobita: Now, relax. It's zero-gravity so that's why everything is upsidedown. (Shizu-chan freaks out) You'll get used to it. When you do, it'll be fun.
Shizu-chan: It can't relax. I want to go home.
Nobita: Wait, wait. (Brings out juice bottle) You want to drink juice? (Opens and the liquid is in the air like jelly) It becomes a glob and rises in the air. Drink, Shizu-chan (Nobita starts drinking)
Shizu-chan: No, I'm fine.
Nobita: Hurry and drink. It'll stick to your clothes. (Starts drinking the juice near her clothes and freaking her out. She tries to run but smacks her face into the desk and starts crying)
Shizu-chan: I want to go home!!
Nobita: Wait, wait...I go to the toliet.
(In the bathroom) It's hard to aim...AAH! The pee is becoming polka-dots.
(Nobita comes out covered in either water or his pee. He goes back to his room)
Shizu-chan: よらないでシッシッ。
Nobita: I know.
(Nobita farts and it sends him flying towards Shizu-chan which then knocks her towards another direction)
Shizu-chan: Don't come here!!
Nobita: I can't control it.
(Shizu-chan throws towards him the large gravity machine. They are about to collide in a fast pace)
Nobita: The machine!! (He looks scared. They indeed collide and everything falls to the ground leaving the house a mess. Nobita's mother comes back and makes him pick up everything. Doraemon walks in on Nobita's mom scolding him while Nobita looks in pain picking things up)
Mom: By making things zero-gravity, your own body now feels heavy.
