With the 4M Water Rocket Test Kit, you can assemble and launch the rocket yourself with just a bottle, water and a pump. It takes off 30 meters upwards when air is pumped into it. The kit will show Newton's third law in physics to children from the age of 10.
Follow the instructions with the pictures to assemble the rocket and launch it in the open. The manual also contains safety recommendations, interesting facts and explanations of the principle of operation.
The set of the Science series gives children the opportunity to assemble an interesting scientific model and test it. In the process of such a cognitive game it is easier to understand the physical principle, and easy to consolidate theoretical knowledge. This arouses interest in further study of science. Children's scientific experiments develop thinking, intelligence, ingenuity, attentiveness, design skills. Children spend time without gadgets, see the results of their efforts, become more focused and confident in their abilities. The scientific kit is suitable for assembly at home, at school and in STEAM educational courses.
What happens at launch? When you pump air into a bottle, it rises through the water and compresses at the top of the bottle. The pressure inside the bottle gradually increases. As a result, it becomes so high that the plug is pushed out. Then the air pressure pushes the water out of the neck of the bottle at high speed.
Why does the rocket take off? The rocket takes off due to the scientific principle according to which any action generates resistance. This is Newton's third law. As the bottle pushes the water down (this is an action), the water pushes the rocket up (this is an action). This way the bottle soars into the sky.
Equipment: plastic bottle (rocket base), 4 stabilizers (including 1 spare), bushing, stabilizer holder, Presta adapter, Schroeder adapter, bushing adapter, long plastic tube.
In addition, you need a bicycle pump with a thumb lock, which is suitable for Prest or Schroeder valves.
