A Disney "stormologist" (seriously) seats 30 guests per showing. They face two large screens that reveal a suburban neighborhood scene. Eventually clouds gather, winds build and general bad-weather havoc ensues. Porch screens rip, shingles fly, garage doors buck, utility poles fall, etc. The damage is extensive, but there's also a little toilet humor thrown in.

The 3-D effects are mildly startling, not as powerful as other attractions that require special glasses. The "4-D" consists of lighting tricks, spritzes of moisture and rumbling beneath the seats.

It's not too harrowing -- not nearly as spooky and threatening as Twister at Universal Studios. During previews, I heard a cast member say it wasn't recommended for guests younger than 7 years old.

Once that storm passes, the group is polled about construction techniques. The eight questions deal with options for roofs, doors and windows. Guests vote on individual screens at their seats, and the most popular choices are then programmed into a screening of Storm No. 2.
