Unique cyclone tube: Made of ultra-light aviation aluminum, with clear anti-slip texture on the surface, unique anti-injury design, and hard connecting tube that can better connect to 1 liter, 2 liter and other larger capacity bottles (to connect other bottles, you need to remove the small plastic ring on the bottle mouth to prevent leakage).
Tornado in a bottle: Connect tubing to a bottle that's about two-thirds full of water and another empty bottle. Shake the bottle horizontally 4-5 times until you see a vortex inside. This is the tornado in a bottle. You can also add coloring or laundry detergent to the water to create tornadoes with different colors or bubbles for a more interesting experiment.
Tornado Kit: 1 Tornado connector, 2 transparent plastic bottles with scales, 2 leak-proof water rings (built into the connecting tube), 1 Tornado instruction manual, and 1 gift box.
Tornado toy: Suitable for teaching, family learning, experiments and group activities. It is a good prop to cultivate children's scientific literacy, prevention of natural disasters and self-rescue.
Water Vortex Cyclone Tube: A CPC-compliant scientific toy, packaged in an exquisite gift box, perfect for gift giving. It's a great gift for birthdays, awards, Christmas, and other holidays.
