If there is one thrill ride that is so common that just about every medium to large fair has one, then Gravitron is it. Gravitron is a ride manufactured by Wisdom Rides and is basically an updated Rotor ride. The ride debuted in 1983 and quickly became a hit on midways due to its high thrill factor and ease of transport.
The ride is stylized as a UFO and goes under three general names: Gravitron, Starship 2000, and Alien Abduction. The outside features quite a bit of lighting along the back flash and UFO. The ride originally used turbo lights but newer models are outfitted with LEDs. Artwork varies but it’s almost always space or alien related. Gravitron models sport a light board below the “Gravitron” signage that flashes the word “Thriller.” I have seen it say different things, however (such as the show’s name.)
The inside of the UFO has multicolored lights running along the ceiling sweeps and typically has a couple of speakers blaring music. The roof of the UFO is simply adorned with a canvas and the walls are made up of slanted, individual panels that riders stand against. In the center of the UFO is the ride operator’s control booth.
First you board the UFO and stand against one of the 45 padded panels; the panels are angled so riders kind of lay back onto one. The ride op mans his position in the center, immune to any g-force, closes the hatch and starts the ride. The UFO starts to spin…and spin…and spin some more until the riders are stuck to the wall.
On an old Rotor type ride, the floor would mechanically lower upon reaching a sufficient speed. On Gravitron it works a bit differently; at a certain speed the panels slide up the wall due to the centrifugal force pushing on the tilted panels. Since the riders are on the panels, they rise up as well!
DoD3 ProTip: Don’t ride this if you have sunburn!!
Needless to say, the G force from the spinning push your face back a bit. With some sunburn on ones face (like I had one time) the ride isn’t very pleasant at all!
