Metallic cube, spinning on all axis, reflecting light and changing shape, dropping tear drops underneath

Metallic Cube rotating on all axis reflecting light dropping tear drops shapes below it

I was taking my dog outside in my backyard on a crystal clear day when I noticed to the north of me something metallic reflecting light in the sky about 500-1000ft above me. It looked like a metallic cube one second, a sphere another, then changed or morphed into several geometric shapes while reflecting light from its different axis it was spinning on. I got my phone and started to record it. It traveled north to west to south. As it was traveling north to west it looked like it was dropping perfectly symmetrical or geometric white tear drops, looked kinda like Pac Man pellets. As it traveled south it shot up probably 3-4000ft kept spinning and it either vanished or my phone wasn't able to focus on it. It made no sound. It looked like a 3 dimensional metallic cube/sphere morphing, reflecting light off all axis it was spinning from. I have four family members that are pilots (private and military) and they don't know what it is. I honesty don't think it was a weather ballon, or drone, or plane, or helicopter. It blinked in and out of existence while it was rotating on its axis reflecting light. The two videos are the originals and were shot with an iPhone X at 4k.
