Check out this amazing and fully functional 90,000-piece LEGO roller coaster that was build by “Lunatic Sekai” to look like the wooden El Toro coaster at Six Flags Great Adventure theme park. The thing is 21 foot long and is truly a marvel to observe while operating.

This is a pure Lego Wooden Roller Coaster inspired by El Toro at Six Flags. Model is made out of little under 90 000 pieces and took nearly 800 hours to build. It is 6,5 meters long 1,2 meters wide and 1,4 meters tall. It has a 26 meters of track which in reality is about 1200 meters long and 60 meters high. The biggest issue with the track was getting the angles right so it will make it over the hills, but won’t derail. Huge variable wit the functionality is temperature and humidity which affects friction and the speed of the cart.
