北京科學中心的彩虹

說著說著，彩虹不見了，一個展項出現在JOJO面前。

“咦，彩虹呢？”JOJO問。

彩虹：“你看，白天我就是這樣為大家展示的。你試著操作一下，看看能不能找到我？”

As they are talking，the rainbow suddenly disappears，and an exhibit is presented in front of JOJO.

JOJO： Hey，where is the rainbow？

Rainbow： This is how I perform during the day. Try if you can find me.

JOJO turns on the flashlight，letting the light shine towards the glass plate，slowly moving the flashlight 30cm from the glass surface，and soon he finds the rainbow.

JOJO打開手電筒，讓光照向玻璃板，在距離玻璃面30厘米處慢慢移動手電筒，很快就找到了彩虹。
