package contains: Each bag has 20 Tornado bottle connectors in 5 colors, of which 4 are red, 4 are blue, 4 are yellow, 4 are green, and 4 are purple
Material: Made of plastic, the connector has a striped surface so it is easier to rotate, can be reused, and is suitable for most bottles
To use: Connect a bottle about 2/3 full of water to an empty bottle, shake the bottle horizontally 4-5 times, and watch for swirls forming inside the bottle
Education: This is a great educational and fun experimental activity tool for children to explore some of the scientific properties of air and water and stimulate their interest in physics, dynamics and potential energy
Applies: Dye or laundry detergent can be added to the water in the bottle, so the resulting tornado will have different colors and bubbles, which will bring more fun. This is the perfect Christmas, birthday and other holiday gift for children
