That was such a fun experience for me too. Congrats on your new world record. Here’s one more surprise: EVERYONE GO SUBSCRIBE TO FLETCHER’S CHANNEL!!!! (also congrats on all your new friends :) Update: he had 2 subs when I wrote that comment and I was one of them. He's now at 13k! Keep it up!
The absolute BEST part of this video isn't any of the experiments. It's the pure, selfless humanity of everyone involved. You don't need to agree with someone to be kind, caring, and compassionate. Thank you for being one of the few who routinely displays that in their content.
Honestly mark is one of the best people on this platform, to bring so many people together for a kid and his family who have been thorough what is hopefully the worst year of their lives is stunning
Just seeing this three years on. Praying that Fletcher is still in remission and living a normal life. This was truly wonderful and inspiring. What an incredible gift for a kid, and family, that have been through a lot. Not sure that you know the impact such things can have on a person undergoing serious medical treatment. Your video call prior to chemo could have literally made the difference between success and failure. Thank you so much. Faith in humanity partially restored.
You prompted me to try and look Fletcher up. There's no recent information about him but based on some older articles, he did end up making full recovery.
This is one of the best videos on UA-cam. First, I'm overwhelmingly happy to see Fletcher doing better and in high spirits. Second, I'm 36 and wish I had a party like that. What a great way to take someone you love and are passionate about to turn it into something special for not only Fletcher and his family but myself also. I was extremely depressed from my father's passing and a recent divorce and I literally smiled through this video. I even got out of bed and ate something and plan on getting out of the house today. You are truly special and I'm happy to see everyone enjoying themselves. Plus, that's the coolest way I've ever seen a Tesla being used. With love. B
Can we just appreciate how this man - never clickbaits us - has amazing videos -tries to help the environment -tries to help people all around the world Thanks, Mark
Mark Rober is the embodiment of “I’m going to to this really extreme thing and not hurt anybody unless they are stealing my packages but even then it’s just going to be glitter”. This was so wholesome to watch, thanks for making Fletcher’s day.
Most celebrities call a kid for 10 minutes and sign a poster. Mark spent 8 months building a contraption, discovers a new compound and gives him *two* world records
What must Mark Rober's mum have said to him as a child? "Mark you've blown up the farm and Grandma's bungalow AGAIN and buried your fathers truck in lime green foam. Now go clean it up and get washed for dinner."
I love when something is super over-engineered for a problem like he was saying they had to make it so it was stronger on the sides, and then something out of the blue happens like it actually flew in the air. Definitely a critical oversight
The fact he talks about him discovering devil's toothpaste in such a casual way surprises me, because he literally just created something that hasn't been done before
I am a former patient at St. Jude Children's Research Hospital for a brain tumor and it warms my heart to see Mark spend so much time and effort to brighten up Fletcher's Birthday. Keep on fighting Fletcher!
I am a 45 year old man. And I have ZERO issues admitting to the fact that I spent most of this video actually crying. Because it is the COOLEST thing that you Mark, and so many others, came together to blow this kid's mind, heal his heart, and make his day! Thank you for showing, in slo-mo, just how good people can be.
I know this comment will probably get lost, but Mark Rober you have been a huge inspiration to me, and have inspired me to create my own science based UA-cam Channel. I met you at VidCon 2019 where I talked with you about a way to run on water that I was developing (I am still in the process of doing that). You're doing amazing things for the world. I hope that one day I can work on some sort of invention/project with you. Edit: I think the next video that I make will be trying to figure out your formula for devil's toothpaste.
Why can't more UA-camrs be like Mark Rober, Dude Perfect, and MrBeast. With their kind and loving hearts they can change the world. Thank you for being so great.
It honestly is so amazing how mark is so humble with everything he has and does! He could easily show off his money like a bunch of other youtubers, but he chooses to help others with what he has!! He is an inspiration to all!🙏🙏🙏
Blues Ghost, But like c’mon he just spent a bunch of money on this video to make one boys life a little better after dealing with a brain tumor... Even if he did flex his Tesla a little bit, he still always does so much for other people!
Skye playz - Kindness has little to do with how much money you give away tf? Edit: Not saying Mr Beast isn't kind, just that he isn't on the same scale with what Mark has done and just how much impact Mark has made on people and especially his young family members. Mark Rober is a legend

What do you mean trying. He already is
