?Interesting experimental tool?: Use it with your children to make a tornado in a bottle, which not only brings unlimited fun to the child, but also improves the child's ability to do hands-on and cognitive science in the process of playing. | ?Educational Helpers?: For school classes, home students, and any other group, this is a great tool for educational and fun experimental activities that stimulate a child's interest in learning scientific knowledge, laying the foundation for enhancing students' creativity! | ?Easy to Use?: Fill the water first to two-thirds of an empty bottle, then use the bottle connector to connect the two bottles, and shake it vigorously for three to five times. The tornado you expect is formed, so easy. | ?Various Tornadoes?: You can add dye or laundry detergent to the water in the bottle so that the resulting tornado will have different colors and bubbles, which creates even more fun. | ?Interesting Gift?: For kids, it is the perfect gift for Christmas gifts, birthdays, and other holidays.
