北京科学中心的彩虹

说着说着，彩虹不见了，一个展项出现在JOJO面前。

“咦，彩虹呢？”JOJO问。

彩虹：“你看，白天我就是这样为大家展示的。你试着操作一下，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打开手电筒，让光照向玻璃板，在距离玻璃面30厘米处慢慢移动手电筒，很快就找到了彩虹。
