Quả cầu lăng kính

The cube shape throws these tiny red, green, and blue rainbows across my wall when the afternoon sun hits it, which is way more interesting than the flat rainbow a normal hanging crystal gives you. I keep it on the kitchen sill and it's become the first thing I look at with my coffee.

Sat these on my kitchen windowsill and by afternoon there were little red, green, and blue patches crawling across the wall. The glass is heavier and clearer than I expected for the price. My kid keeps repositioning them just to watch the colors move.

These prism cubes split sunlight into red, green, and blue bands that dance across my kitchen wall every afternoon. I've got three sitting on the windowsill, and honestly the color separation is way crisper than I expected from something this small. Hours of free entertainment for my cat too.
