A 6″ fidget spinner powered by three E sized rocket engines. Most impressive.
The spinner has a 6 inch radius, so it travels ~37 inches to make a full circle. Its spinning 88 times per second (5200 per minute), so that means the tip is traveling 276 feet per second, or 188.182 MPH. so yeah, 1000mph fidget spinner is pretty much impossible… Who will accept my challenge?
