這款小巧的太陽能裝置能將陽光化為彩虹。使用吸盤將彩虹製造機固定在窗戶上，當陽光照射時，會啟動太陽能馬達，帶動懸掛的水晶開始旋轉。光線穿過水晶的切面，繽紛的彩虹圖案便會灑滿整個房間。
我們每天都很期待「彩虹時刻」的到來——當太陽在天空中移動到特定位置，就會引發一場五彩繽紛的派對光效，這也意味著我們的工作日正式結束。隨著季節變化，可能需要重新調整彩虹製造機的位置，因為就像真正的彩虹一樣，這台裝置需要直射陽光才能運作。它是任何窗戶的魔法點綴，也是送給喜愛物理或自然的朋友的絕佳禮物。
無需電池。
Stuck this on the kitchen window with the suction cup and now my whole counter gets a rainbow every sunny afternoon. The solar motor kicks in on its own, no batteries, which is exactly what I wanted. My kids keep trying to catch the colors with their hands.
Bought this for my daughter's room and she loves watching the little motor spin up whenever the sun hits it. The suction cup holds fine on clean glass, though it slid a bit on a dusty window until I wiped it down. Rainbows only show up on really sunny days, but that's kind of the point.
