Julie playing tomb keeper

Julie, a 20 year old college student, was babysitting two rambunctious boys ages 11 and 14, for the weekend while their parents went out of town. She mistakenly agreed to play a game called crypt keeper. Before she knew what was happening, her arms were bound tighlty behind her back and her torso wrapped in duct tape. She tried convincing the boys to let her go but they pulled off one of her socks and stuffed it into her mouth and tightly wrapped duct tape over her mouth, effectively silencing her. Luckily they ran out if duct tape before they could finish wrapping up her legs together. Can she find a way to escape her bonds before the boys come back with more duct tape?
