Cement Tumbler Corridor

Here is another installment of exTRAPaganza, our Thursday over-the-top trap series. 

Almost everyday I see a truck from Central Concrete driving down the street.

The characters enter a cylindrical corridor, sloped downward. The floor contains gravel and sand. As the characters make their way down the corridor, it starts to first slowly fill up with water, which happens to be filled with nastiness. Soon after, the corridor begins to rotate, sending water, sand, gravel and characters flying. Slowly, the heat begins to build up, and the sand and gravel form a concrete-like substance, trapping the characters.
