Sure, this tornado demonstration model is meant for classroom use, but do we ever really stop learning? We're on a neverending quest for knowledge, enrichment, and neat toys — call it the classroom of life. Whether you're a kid or an adult, this thing is sweet: a chamber that sits on a lab bench or computer desk and creates a small-scale tornado. Witness the power that has tossed innumerable Midwestern cows and fences high into the air and has inspired at least one really mediocre Bill Paxton movie, all without leaving the comfort of your swivel chair. Plus this thing will make the bobble head collection of the guy in the cubicle across the aisle look really crappy in comparison. Nerdy office dominance can be yours for only $204.
