Robinson Foundry created these not-so-stealthy shurikens which glow in the dark. He created the design on his computer, 3D-printed forms for sand casting, then filled the molds with aluminum bronze. After finishing, he added a mix of epoxy resin and strontium aluminate, which glows brightly after being exposed to light.
