Insane LEGO Roller Coaster

This absolutely jaw dropping roller coaster is on display at Hamley's in Prague, Czech Republic starting next month. I don't have many details on it, and no time to gather them but according to the video it's 90k pieces with 26 meters of track. And yes, that's LEGO track, but it's been modified with a heat gun and a ton of patience by builder Chairudo.
