Gravity Chamber Descent

I bolted across the metal threshold right into the center of the shiny chamber! With a soft hiss, the heavy brushed doors slid shut behind me, sealing me inside. Suddenly, the entire floor dipped under my boots—whoa, my stomach gave a giant flip like soaring off a cliff! Instead of losing balance, I dropped straight into a wide, grounded stance, digging my heels hard against the slick speckled granite. The stainless steel walls rattled with deep vibrations as cool air rushed down from the ceiling vent. Riding this roaring moving room all the way down is wild!
