Writing prompt full of suspense

Let's talk a little more suspense. Now that we know the difference between mystery and suspense, how do we create suspense?

Use time constraints - A key method to building suspense is through the use of time. The protagonist works against the clock, and the clock works for the villain.

Keep the stakes high - The story must be about a crisis that threatens to rock the foundation of the protagonist’s world, and the hero must be willing to do anything to prevent it from occurring.

Complicate matters - Pile on the problems. Give the protagonist more things to deal with than he/she can possibly handle.

Apply pressure - The protagonist works under what seems to be insurmountable odds. All his/her skills and strengths are stretched to the breaking point in order to save the someone's life, his/her own life, or life as they know it.

Be unpredictable/surprise us - Nothing in life goes according to plan. Make nothing straight-forward for the protagonist. Suspense requires twists and turns.

Now that you have a few tips on how to create suspense, let's write it. Use the tips from above to help you write a paragraph or a page, or whatever comes to mind. Make the reader want more!
