It will take a bit of skill, but no doubt, this is one cool Easter Egg. In the training mode of Wii Sports Bowling, you are able to try your luck against an ever-growing number of pins, capping at a 91-pin setup. Rather than going for broke trying to legitimately knock down all 91 of those bad boys, you can apparently trigger an explosion of atomic levels if you just send the ball straight down the bumper. Check the video to see what we mean.
