This tutorial video will show you how to build a hovercraft using plywood, a leaf blower, and various other materials. This hovercraft works best on a smooth, flat surface.
Making little robots with a LEGO Mindstorms NXT set is already cool, but putting one underwater? Now that's just crazy. That didn't stop this engineer, who built a LEGO submarine that can not only maneuver around his fish tank, but can also be remotely controlled with his Xbox controller.
Using a LEGO Mindstorms NXT kit, a pair of awesome engineers put together this fully functional replica of the Curiosity Mars rover. Not only is it built completely out of LEGOs, it's motorized, programmable, and ready to explore the far reaches of your living room.
If you played with K'Nex as a kid (or still do), you know that it can take a lot of those tiny little pieces to build something. Just imagine how many it must have taken to make this full-sized, fully functional, coin-operated skeeball machine with a mechanical score counter.

So very pointless, yet unquestionably spectacular. The best kind of "art" performs no other function than to delight the viewer, and Japanese YouTube user Denha's complex marble machines do just that. But are marble machines art? You can call them that—or toys, scientific contraptions, engineering feats—but however you choose to label them, the best marble machines are complicated, skillfully crafted, and driven by the principles of potential energy, kinetic energy and gravity.
Are you looking to build a cool home science experiement? Why not try out a Stirling engine? Wait, what IS a stirling engine? Well... a Stirling engine is a heat engine operating by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work. This project was made from parts around the house and you should be able to do the same. This is a great project to explain how gears work,...

Mike Doyle's latest LEGO house (perhaps even more hauntingly beautiful than the last) is a Victorian mansion that transcends the material so effectively, the plastic reads like real rotting bricks and mortar. Beautiful house-devouring trees, created with LEGO hinge cylinders to mimic the texture of tree bark, and ridged 3 mm hose, droid arms and other technic connectors for the creepy, spindly branches.
Paul Yperman, you've got some competition (see previous entry, Star Wars LEGO Droid Ship). 15-year old Sven Junga's LEGO Stargate diorama (including a Daedalus from Stargate Atlantis) is nothing to shrug about. Incredibly impressive.

The Stilzkin Indrik is a mighty, mini LEGO Russian crawler, capable of lugging heavy loads over snowy terrain: "It has a large contact surface, which prevents it from sinking into the snow. It offers great traction on almost any surface, and loads of torque to get out of tight spots."
Build your own miniature gryocar from a toy gyroscope in this fun little project with Kipkay and make it ride on skinny tracks! All you need is a toy gyroscope, a spraypaint canister top to fit the gyroscope assembly, and some assorted parts that you could probably find around the house (or at your local hardware store). Ask your parents for permission first!
Apple software engineer Andrew Carol built a fully-functional replica of the Antikythera Mechanism, the world's oldest known scientific computer. The 2000-year-old analog device was used by the ancient Greeks to predict the year, date, and time of future solar and lunar eclipses accurately to within two hours. Carol put together the 110 gears (made with 1,500 LEGO Technic parts) in just 30 days. See how it works below.
It took him a year to build and about $30,000 in parts, but Steve Hassenplug has created a truly magnificent robotic chess set, inspired by the magical chessboard in the first Harry Potter movie.
You can almost feel the pain of Dave Kaleta's outstretched, dissected frog (which is pretty incredible, considering it was constructed with those tiny, plastic bricks we call LEGOs). Kaleta's work of LEGO art was built for the MOCPages MOC Olympics.

In this tutorial, we learn how to build a simple mouse trap car. To do this, you will need: a ruler, two records, a thin metal rod, and a mousetrap. First, you will lay the ruler down to measure out where you are going to place the records. Next, you will hold these into place by using the metal rod in between the two of them. If it's not secure, use washers and glue to keep it in the proper place. Then, attach the mousetrap to the middle of the rod in between the records. This is it! Now you...
