Child demonstrates repeatable mass-dependent light behavior using a DIY slit experiment — data publicly released

We ran a simple slit experiment where we held geometry and alignment constant and changed only the material. The resulting light patterns changed in consistent, repeatable ways. 

Under fixed geometry and alignment, changing only the slit material resulted in systematic changes in central lobe width, peak intensity, and outer flux. Full image set (300+), raw measurements, and baseline comparisons included.
