russian roulette. Put a stick fgure in one of the boxes and see if he lives for a minute or if he's the last one that explodes
One of them fused oxygen and I still have no idea how they did that
tldr: slightly more than ~5 sec half life, due to neutrons having random velocity being released by polo
now without guesses: according to source each frame a bomb(from save) has 0.0018/1 chance of neutroning(0.18%), so each second its a ~10% chance of exploding, times 5 says that each 5 seconds, half of them will have released neutrons in a random direction, which plus a offset i haven't measured as it is also kinda random(random velocity neutrons) will be the half life of a material made of these bombs, remember this will variate slightly as it uses RNG
after you asked i through about it, and i looked simultaneously at 4 of the nukes, then i saw a neutron appear and realized how it works, each frame polo has some chance to spontaneously neutron, which plut hates when it happens and explodes, which also explodes the DEUT into hot angry neutrons
i just counted in my head till about half disappeared
how on earth did you get that
