Build your own high-speed roller coaster with the Screamin Serpent building kit. The Screamin Serpent from K'Nex is a sweet replica of a steel rollercoaster that you can build yourself and bring to life. There are a ton of parts to this coaster and it'll probably take you a few hours to put together. The instructions are detailed and quite clear but you may need some help from your parents. Once you've built the coaster track with all its twists and turns, you just pop the three cars onto the track, and turn on the motor. The plastic chain will slowly haul the cars to the top of the coaster, before sending them screaming down the track with super cool sound effects. The Screamin' Serpent is fun to put together, fun to watch in action and it's totally massive. This roller coaster is over 6 feet long, 3 feet wide and 3 feet high, so you'll need some a pretty big room to put it together. If you don't have a lot of space, the kit also comes with instructions for making smaller coasters.
