Building Huge K'nex Speed Train!

Today I did a speed train with K'nex. I decided to make a huge roller coaster by purchasing and combining 3 different boxes instead of the model of my dream, in the section included in the #KildhoodDream series. Since the pieces in the sets are incompatible with each other, a cool model has appeared, though not exactly as I thought. Also, in the dark, I made the phosphors of the world more powerful than normal with the most powerful flashlight and obtained a very beautiful image. Have a good time!
