Are you wondering how to make a beautiful rocket that can easily surpass a baking soda-vinegar rocket? It's really fun to make. Why don't you try to make it yourself? Make a great rocket with these great tips and tricks
Steps
-
Invert the bottle and cut three flippers of cardboard. This is necessary to hold the rocket at launch time. Make your best design.
-
Tape them all to the bottle at an angle of about 120 degrees between them . Remember, the bottle must be upside down and the flippers must not be taped at the bottle's base. [1] X Research sourceAdvertisement
-
Make a hole through the cork so that the bicycle pump can easily fit into it. [2] X Research source Fix the pump tube to it with plasticine.
-
Fill the bottle with water to about 1/4 of the total bottle. [3] X Research source
-
Jam in the cork and make the rocket stand. (flippers do come in handy!)
-
Start pumping as much as possible, but do it quickly. [4] X Research source
-
The pressure builds up so much that the cork and the pump shoot out and the water gushes out. Since action has an equal and opposite reaction, the bottle shoots up. [5] X Research source
-
Alternatively, instead of making fins make wings and hold the bottle at an angle for launch.

QuestionWhy do I need to fill it with water? Can't I just use air?Community AnswerWater is heavier than air. This makes water a denser and heavier exhaust, thus allowing the rocket to go higher.
-
QuestionHow come I have to pump so fast?Community AnswerThe gap isn't 100% airtight, so air is leaking out of it. So you need to pump it quickly so that the pressure can build up.
-
QuestionWhy do you need a cork?Community AnswerTo hold the water in bottle as well as to be able to inject the bike pump to get air into the bottle, creating pressure for the launch.
