Death Drop Trap

This trap was made by me. The subject for this test is a girl named Lauren. Now Lauren used to be an average girl. Went shopping, hung out with friends, and snap chatted. However she has recently lost her father. In grief and for money, she has become a prostitute. She uses the money from her job to drink away the problems in here life. Also, she has been able to elude police by knowing how to slip out of handcuffs, as taught by her father. She knows how to stay away from her problems, but now she is forced to be faced with them.

The Trap
She would wake up in a wooden box. However, there is a hole that shows her what is underneath her. She sees that the box is being help up by a rope. But by the rope is a blowtorch. She also sees under the box three spikes lit on fire. She then notices that she is handcuffed.

How this trap works
She has three minutes to break out of her handcuffs and break the box open and jump out, which would result in breaking her legs. If she does not do this, then the box will fall and land on the spikes. If she is still in the box, then the spikes will most likely go through her torso and neck. Not sure about where the third one would go.
