The text is a transcript of a video where the speaker demonstrates how to make a rocket from PET bottles, vinegar and baking soda, following the project of a science teacher who won an award. The speaker explains the science behind the rocket, the materials and steps needed to build it, and the challenges and results of launching it. He also encourages teachers to participate in the Shell science education award and share their innovative projects. The summary is:
- The speaker makes a rocket from PET bottles, vinegar and baking soda, based on a science teacher's award-winning project.
- He shows how to build the rocket and its launch base, and explains the chemical reaction that propels it.
- He launches the rocket several times, trying to reach 100 meters, and records the flights with different cameras.
- He celebrates when he achieves his goal and does a final launch for slow motion.
- He thanks the teacher for his support and invites other teachers to join the Shell science education award.
Here are the key facts extracted from the text:
- The text is a transcript of a video about making and launching a rocket with PET bottles, vinegar and baking soda.
- The video is sponsored by the Shell science education award, which recognizes teachers who use innovative methods to teach science and mathematics in Rio de Janeiro and Espírito Santo, Brazil.
- The rocket project is based on the work of Professor André de Oliveira, who won the award in 2017 and went to London.
- The rocket has a launch base made of PVC pipes, a trigger made of a 40mm sewage pipe, and a cork with a nail to pierce the bladder inside the bottle.
- The rocket has a bladder filled with vinegar and baking soda separated by a balloon. When the nail pierces the balloon, the vinegar and baking soda react and produce carbon dioxide gas, which pushes the vinegar out of the bottle and propels the rocket forward.
- The rocket also has fins made of plastic folders, a nozzle made of another PET bottle, and some mass at the tip to balance the flight.
- The video shows several attempts to launch the rocket, with different results. The best launch reached 159 meters, which was measured by blue EVA markers on the ground.
