Rocket

Collect the Materials

two bottles of two liters each, a cardboard box, scissors, a cutter, black tape, a wine bottle cork, a valve to inflate balloons, an air pump and some water to fill the bottle

First, you will need to cut the top of one bottle and paste it on the bottom of the other bottle and stick them together.

Then, in the cardboard box, the type of wings that the rocket must have must be designed. This design of the wings depends on your creativity but, regularly, in this type of rockets the wings are triangular, and once you have the design do it three or four times and you cut them.

In the middle part of the rocket, with the black ribbon, the wings are symmetrically attached so it does not affect the aerodynamics.

At the end, you will have to put the valve in the middle of the cork, then fill ¾ of the bottle with water, and put the cork in place of the lid and then proceed to perform the experiment.
