We filled a swimming pool with 25 million Orbeez so I could settle an argument.

Mark, just stumbled on your YouTube channel yesterday, starting with the Pinewood Derby video. I loved the post about the actual, representative size of the solar system (and was wowed that you filmed it at my wife's high school). Keep up the great work - I subscribed after the second or third video and will enjoy watching with my little girl (who I hope will be an engineer or scientist one day).

Seriously. THANKS YOU guys. Here's a highlight reel of my favorite bits of the past 4.5 years that we've collectively shared.

+Mark Rober Thank you so much! You've had a very influential role on my choice of major. Like you, I fell in love with physics my junior year and I thought there's no way this can get any better. Then, I found your videos and your story and realised just how cool this field is. So I handed in my application for a few schools under mechanical engineering and now I'll be pursuing it at Valparaiso University!

I heart space but sometimes it can be hard to comprehend. I try to fix that in this video with junk you can find lying around your house. Also, if you’ve wondered how there could be a ninth planet that we’ve never noticed till now I try to clear that up too by demonstrating just how impossibly far away it is.

Here are 4 steps to defog your windshield twice as fast in the morning and the science behind why it works. Thanks for watching from the bottom of my nerdy heart.

If you've ever wondered how to safely land an egg from a 3 story bridge, I've got you covered in this video. My next video will be about inventing a time machine so I can go back to my High School Physics class to secure the Egg Drop Competition title.

Hey Mark, I was wondering if I could get detailed instructions on how to build the straw man as the ones in the video seemed to fast and I'm doing an egg drop experiment at my middle school. If you can, it'd be greatly appreciated if not, then I understand.

Some helpful science if you ever find yourself face to face with a grenade :)

Can we talk about co-inventing? I'd like to discuss a simple mechanical idea with you, but I'm trained in CompSci.

Here's how to make a Snowball Machine Gun that can fire 13 snowballs in 1/2 seconds. It's a must have in any respectable Uncle's arsenal.

Thanks for the idea. We did this for our church picnic. It wasn't very difficult at all. We would love to send you pictures of our finished project.
