Brainstorm - My Very Own Rainbow

Bring nature’s most beautiful light show indoors with the Brainstorm My Very Own Rainbow projector.

This enchanting STEM toy uses multi-coloured LEDs to project a vivid, arcing rainbow across walls and ceilings in a darkened room.

Beyond the electronic projector, the set includes a natural sunlight crystal that creates shimmering rainbows when placed on a sunny windowsill, bridging the gap between artificial light technology and natural optical science.

Summary Founders take: This is one of our favorite double-duty toys. During the day, the crystal teaches kids about refraction using actual sunlight; at night, the LED projector becomes a soothing, magical nightlight. It’s a fantastic way to calm "fear of the dark" while sparking a genuine interest in how light and color work.

Who This Is For (and Who It's NOT For)

• Great for: Children who love "room decor" STEM, kids who need a comforting night light, and young scientists curious about light and weather.

• Not ideal for: Rooms that cannot be made completely dark (the LED projection needs a dark environment to pop) or very young toddlers who might misplace the small sunlight crystal.

Honest Pros & Cons Pros:

• Includes two ways to play: an LED projector for night and a crystal for daytime.

• Features an auto-shutoff timer to preserve battery life—perfect for sleepovers.

• Includes a "secret code" to unlock educational facts and activities online.

Cons:

• Requires 4 AAA batteries, which are not included in the box.

• The projection brightness depends heavily on the distance from the wall and the darkness of the room
