Deep dive into the workings of a 19bit marble computer. You'll learn digital logic, binary numbers, and how to build your own marble computer.

Part 1: How I built the marble computer:    • I Made a 19bit Marble Computer (Pt 1)  

Learn how to read & add binary numbers, and discover why computers use them as we delve into the workings of the world's largest working marblepowered computer. You can see the marbles roll as they perform the calculations! It's pure STEM edutainment with Chris and his laughable friends in this video that combines math, engineering, and GraviTrax marble run fun.

This video makes a great homeschool lesson. You and your kids will:

* Learn the basics of binary numbers (MATH)
* See how binary math is implemented in digital computers (COMPUTER SCIENCE)
* Examine the computer's physical design and inner workings of the marblepowered circuits (VISUALIZATION)
* Receive free step by step instructions to build your own GraviTrax marble computer (HANDSON LEARNING)

How can this digital marble computer add to over 1 million, despite having only 180 marbles? And what is the Vortex of Doom?
