Or do what I did last night. They had their sabers out at bedtime in their room. The older boy had an oppressor and the younger 1 yr old had his star wars light up m&m saber. They were duking it out so I went into my room donned my Jedi robe, snuck down the hallway, my wife flicked out their lights one second before I jumped in and ignited my saber. :D
Not great to scare your kids rigth before bedtime but all loved it. :D
You could try that too. ;D
