hudiemm0B Optical Glass X-Cube Dichroic Cubes Prism RGB Combiner Splitter Educational Gift

Fascinating fun for 11 year old but wish it were 4X bigger!

Need a small light source (pocket flashlight works great) and these cast light just like the pics. Great for understanding prisms and light's behavior.

I recently purchased this 6 pack of RGB PC fans and I couldn't be happier with my decision. The fans are incredibly easy to install and fit perfectly in my computer case. The RGB lighting is also very bright and vibrant, making my PC look amazing.One of the things I love about these fans is how quiet they are. They operate silently and don't add any unwanted noise to my system. They also provide excellent airflow, which has helped to keep my system running cool and stable.The fans come with a remote control that allows me to easily adjust the RGB lighting and fan speeds. I can also control them using my motherboard software, which gives me even more options for customization and control.Overall, I would highly recommend these RGB PC fans to anyone looking to add some color and excitement to their computer system. They are a great value for the price and provide excellent cooling performance in addition to their stunning RGB lighting. If you want to take your PC's aesthetics to the next level, these fans are definitely worth considering.

I have dichronic glass from other things. Itsreal. Hard to tell by pics since they all recycle images and some look like plastic. Arrived well before the tracking said
