Forget about terrible singing when it comes to birthdays, as the Musical Cake Tray offers a playable Happy Birthday melody as long as the quartet of AA batteries within still have some juice inside. It will also prevent fights from breaking out as it helps you cut the perfect slice of cake without looking as though you were biased against your neighbor’s kid to give your own progeny the biggest slice. LED lights around the perimeter will let you know just where to cut. As long as the cake is no larger than 12″ in diameter, the Musical Cake Tray takes the, er, cake for today.
