Is it possible to escape this room? (episode 2)

You make it through room one miraculously. The door slams shut, and the water runs down a drain in the floor where you’re standing. You are now standing on a platform overlooking a room 20 ft long by 20 feet wide by 50 feet deep. The floor of the platform is 20 by 10. It’s just a 3 inch thick steel plate built directly into the structure of this building. It’s 10 feet to the ceiling standing on the platform. On the platform with you is an empty plastic 55 gallon drum. Starting at the edge of the platform is uncooked rice.

On the platform is a diagram. It shows a human figure standing on the platform reading the diagram. The diagram is a bisection of the room. The rice is shown going all the way to the bottom of the room where a door is represented with an exit button.

Can you escape?

There is no water from the prior room. You still have your ice axe…
