Professor Screamore's SkyWinder is an upcoming renovation of the previous steel inverted roller coaster, Mind Eraser, located at Six Flags America in Upper Marlboro, Maryland, USA. Opened on May 20, 1995, it is a standard Suspended Looping Coaster installation from Vekoma. For 2024, the coaster is being refurbished and the trains replaced.


Mind Eraser opened on May 20, 1995.

In 2017, Samsung Gear VR virtual reality headsets were used to offer the Galactic Attack Virtual Reality Coaster.[2]

Mind Eraser was removed from the park's website in 2022, with no comments about it from the park itself.[3]

In 2023, Six Flags announced that Mind Eraser would be repainted and will be given new trains as part of an overhaul of the Coyote Creek themed area which will be replaced with SteamTown.[4] In May 2024, the new name Professor Screamore's SkyWinder was announced.[5][6]



Color scheme

Yellow track with orange supports. Prior to the 2005 season, the track was teal and the supports red.

Ride experience

After the train is locked and checked, it moves out of the station, towards the 109.3 foot chain lift hill. Then, when the train crests the lift hill, it makes a rightward U-turn drop. Next, the train goes through a roll over. Then, it makes a slight turn to the left, before a sidewinder. After the sidewinder, the train makes a 270 degree helix to the right, before a double in-line twist. Then, the train makes a U-turn to the right, before a dip. Finally, the train hits the brake run, before the train makes a right turn to the transfer track. The ride ends when the train makes another right turn to the station.


2 trains with 10 cars per train. In each car, riders are arranged 2 across in a single row, for a total of 20 riders per train. The train originally had eight cars, but at some time the park extended it to ten.
