Electric motors can seem very mysterious! How do they use electricity to start rotating? Let's break it down step by step to understand how it works. Topics covered in this video: circuits, current, magnets, electromagnets, armature, commutator, brushes, stator, and rotor. This video only covers DC motors.

We use it all the time but most people have never actually seen the inner workings of an escalator!  

Summary: I've animated the inside to give you a detailed look at the steps, step chain, gears, handrail, and the motor.  My favorite part is how the steps always stay level when they're on top.  In this video we also take a look at how escalators layouts such as side by side or the criss-cross configuration.  And yes...they really do have spiral escalators!  Maybe I'll cover that in a future video.
 

The most fascinating technology in the Star Wars universe is the lightsaber. In this video I show you how they work! Okay so...lightsabers aren't real...but it's still fun to think about. Thanks for watching!

Gumball Machines! How do they work? Let's find out...

The Burj Khalifa is currently the tallest building in the world! (as of 2018) This video shows you all about it - surrounding landscape, shape of the building, what the floors are used for, elevator system, and comparisons to other tall buildings.

The International Space Station is the largest man made object in space. It was built in pieces and then launched into space and assembled in orbit. In this video we'll go over some background about the station and then walk through each module in the order that it was assembled. This animation took a long time to make - enjoy and please share your comments with me!

The Mercedes-Benz Stadium is unlike any other stadium in the world! This video goes through in detail all the different levels, the halo board and retractable roof.
