3D3DMechanical MagicCube.
Mechanically (pyrotechnically) fired GE MagiCube flash cube. Remarkably, these flash bulbs have no electrical contacts. A thin tube filled with contact-sensitive explosive (I would guess mercury fulminate) leads into each bulb, and is set off with a sharp knock on the bottom.
