Preface:

In today's society, where children's education is increasingly valued, scientific enlightenment education has gradually become an important topic in the field of education, which is pursued and explored. More and more teachers and parents are beginning to pay attention to cultivating children's scientific literacy from an early age, so that children can develop good personalities and behavioral habits from the beginning. Parent-child interactive crafts can improve the quality of parent-child companionship, improve the relationship between parents and children, and we spend time with our children, without mobile phones, iPads, or televisions, only joy, interaction, and communication. It can cultivate the ability of children to solve problems by themselves. When children encounter problems, they should first see and experience the solution themselves, because parents and teachers solve problems in the process of doing crafts. It can develop children's imagination. In children's world, cars can fly in the sky, and the sun can be green.

Experimental Purpose:

For water rockets, the launcher: 56*34mm, threaded nozzle with double rubber rings: 40MM*33MM, using a bottle with a 28mm diameter mouth.

A water rocket is a toy designed to utilize the principles of mass ratio and atmospheric pressure, and it is also one of the famous cases in physics teaching. It can help to cultivate students' interest in physics learning, and the underlying physical principles are an important foundation for understanding mechanics in physics.
Water rockets, also known as air pressure-driven water rockets or water-propelled rockets, are made by using discarded beverage bottles to create the power chamber, the body, the nose, the tail fins, and the parachute.
