If you want to learn the process whereby you can make cool stuff too, join in my Creative Engineering class!! Monthly.com/MarkRober

This class is a hands-on, 30-day learning experience that will teach you how to use engineering and science to bring your creative ideas to life.

During this class, I'm going to share with you my entire creative engineering process from start to finish. You're going to follow along with me as I fully design and engineer 3 brand new builds from scratch... from how I come up with the idea, all the way through bringing the final builds to life.

The best part is, over the month, you'll follow along with me and my process, side by side, and you will leave the class with 3 original, creative builds of your own.

This is the class I wish I had when I was starting out. It's designed to take your skills to make cool stuff to the next level, whether you're a beginner or a more experienced maker/engineer.

See you in class!

    @Mark Rober Can you do a cloud seeding PoC as a forest fire prevention option? If it works, maybe California will fund a large scale one and be saved.

    For someone to get 16 million views in 2 weeks, which is absolutely ridiculously awesome! You are the chillest guy on HRless. You go through so much to make people happy. Mark, since I’ve watched your videos, I’ve really had a different look on things and how they work. I would have never though that you could hear a horn from so far away. Even how the simplest things that people drive by all the time which are the grain silos, never new how awesome they are! Carnival games, how smart squirrels are, how far a football can be punted. You’ve covered everything a kid and/or an adult would want to do. My brother has autism and for your son to have autism and for you to make a video of him is extremely difficult because of how people view children and adults with autism. They are extremely smart and honestly they are so much cooler than us! You deserve more than what you have now with the amount of time and effort you put into everything. You probably won’t see this but that’s not why I’m posting this comment, just a comment so people understand just what all you’ve done.
