If only I knew that something like this existed when I was a child, maybe I would still believe in unicorns. (You know you did too at one point.) This Rainbow Projector is exactly as it sounds and it a pretty interesting night-light if you ask me.
The Uncle Milton Rainbow In My Room Projector is the first device I’ve seen to actually produce rainbows inside of your own house. Too bad I didn�t know about this prior to St. Patrick�s day as I could have had multiple pots of gold by now. Even if the leprechauns didn’t show, I�d still be happy that there was a ray of colors streaming across my room. This can turn on with the wave of your hand and uses multi-colored LEDs to brighten your day or night. There is also a bonus window prism disk for real-life daytime rainbows. It costs about $23, and I am more than willing to pay $50 to go full-on double rainbow all the way across the room.
I'm pretty sure my little niece would love this for her bedroom.
