水和油

这是一个将水和油变换位置的魔术。

展示一个有杯子图案的套筒和两个分别有水滴和油滴图案的盒子。先把油滴盒放进筒里，再把水滴盒放进去。拿开套筒再看一眼，油滴盒在下面。轻轻摇动套筒，水和油就会混合在一起，打个响指，就会分离。拿开套筒后，油滴盒竟然在上面。

非常适合给孩子们表演，学习水和油的知识。为什么水和油不会混合？为什么油总是浮在上面？

产品包括：道具盒子和视频教学。

Water and Oil

This is a magic trick that transposes the water and oil.

You show a tube with a cup pattern and two boxes with water drop and oil drop patterns respectively. Put the water friend in the tube first, then the oil friend. When gently shaking the cup, the water and oil friends mix together, and separate with a snap of your fingers. After removing the cup, the oil will always rise to the top.

Great for kids show and teaching them about water and oil. Why don't water and oil mix? Why does the oil always rises to the top?

Comes with the prop and instructional video.
