Have a real tornado right on your desk! You will need an empty plastic bottle and a set for research from 4M. Add a few drops of paint or glitter to the water and watch them whistle in the water funnel. You will get acquainted with the principles of physics and hydrodynamics, study an interesting natural phenomenon without leaving home.
To assemble the mechanism you need: a small Phillips screwdriver, two AA batteries, a plastic bottle and water. You will see how the engine, receiving battery power, starts the propeller. The blades create a vortex in the water, and it begins to rotate inside the bottle. Paint the water dark or add tinsel to make the tornado more spectacular.
Your home tornado will be completely safe, unlike real tornadoes. They are classified as destructive natural phenomena. Tornado & ndash; it is an atmospheric vortex with a wind speed of about 500 km / h, which occurs in a storm cloud and spreads to the earth's surface in the form of a funnel. The force of a tornado can be enormous and lift cars and houses. Explore tornadoes & ndash; extremely dangerous occupation due to their unpredictability. Therefore, scientists are reproducing this rare natural phenomenon through similar models.
This set from the KidzLabs series will be of interest to children under 8 years of age. Exploring the phenomenon of tornadoes, children will gain new knowledge in physics, train design skills, develop imagination, intelligence, curiosity. The presence of adults is recommended during the experiments. In 2015, the research kit received awards in the United States and China for interesting design.
