the left and right mirrors are parallel, so if you stand on one side and look at the other side, you will see an infinite number of yourself in the mirror. .We just use this principle to install a circle of light tubes, through infinite reflection, to achieve the effect of infinite imaging, we can see infinite light bars, and they will become smaller and smaller, and we can create the feeling of a bottomless pit." Then Alice walks into the garden and meets the playing card gardener busy painting the white roses that the Queen of
Hearts hates into red roses. Zhu Qingqi designed an experiment to help gardeners not have to be beheaded. "We apply red thermochromic pigment on some of the white roses, which will turn white when touched by hand; the other part is painted with photochromic pigment, and sms services it will turn red when exposed to ultraviolet light." Anti-counterfeiting technology, temperature warning, ultraviolet intensity in daily life It is shown that this principle is actually applied.

The last level of the scientific adventure, "Flying Cards", comes from the epilogue of the fairy tale, where the angry queen of hearts beheaded with cards. In fact, Zhu Qingqi's inspiration also came from the Discovery Channel program " MythBusters", who had done an experiment on "Can high-speed flying cards kill people?" She and her team built a playing card transmitter with a speed of more than 200 kilometers per hour, allowing five decks of playing cards to be launched at high speed within seconds. After a live demonstration, it has been proved that as long as you stand a certain distance away, the card will quickly slow down due to air resistance, which is not enough to cause harm.
