World's Largest T-Shirt Cannon (breaks the roof)

I was challenged to build a T-Shirt cannon. I accepted the challenge.

Thanks to these folks for providing some of the music in the video:

TWO videos in ONE week!! A true Christmas miracle!!! I'm now going to sleep for 4 days.

Anthony is genuinely going to grow up and be an engineering mastermind. At such a young age, and he already produces amazing engineering creations.

[SuperfastMatt]

Between this and Smarter Every Day's supersonic baseball cannon, I'm starting to think I need to switch to ballistics for real YouTube success.

I think Mark is one of those people that we read about in math problems who buy an extensive number of watermelons.

[Wil_Dasovich]

I am genuinely wondering if that kid is considered a legal genius at his age, or if there are just a bunch of kids that smart out there who understand these type of intricate concepts. Serious question!

[TheRealGuywithoutaMustache]

Anthony, so young but so intelligent and gifted. That kid's gonna go far in life I tell you.

[JackTheBus]

you could just tell that kid’s heart completely stopped as soon as he realized it was Mark he was talking to 😂

[Chaosfife]

Anthony doesn't need a portfolio; he needs to show this video.

And this video alone should be more than enough to get him some scholarships.

"I'm more nervous... about the surprise than I am about actually firing the cannon"

That tells you a lot about Mark's heart.

[johnnyharris]

The explanation of how an actual canon works was so perfect

[Cubick]

Anthony’s reaction was completely priceless, this kid is definitely going to have a bright future in engineering

[valles]

The difference of "tshirt cannon" and "cannon that shoots tshirt" is amazing

[cipher_pd]

Mark is so humble that he actually made me believe that a NASA engineer couldn't figure out how to improve the canon's throw & that he had to get help from Anthony. Nevertheless, Anthony seems like a cool & talented kid.

[mochimonster]

I can't believe Anthony understands the mechanics of such complex things at his age! He understood things that could be implemented to improve the design! You could tell how excited he was when he saw Mark, its just so heartwarming.

[joshuatan]

I've worked a year in the industry as a process engineer and it is absolutely astounding how much this kid already understands. I want this guy to be my boss too!

[Nightstick]

Anthony's got a great grasp on engineering and physics already, he clearly understood the mechanics behind the canon and made great suggestions to increase the power in a number of different ways. I look forward to his world domination!

[misslinh]

The fact that Mark could've probably figured out how to do all the engineering and problem solving himself, but chose to let Anthony have his moment instead.

Восхищаюсь тем, что человек догадался доносить детям инженерию в такой форме, буквально говоря: "смотри, инженерия это не только скучные рассчеты и формулы, но еще и много интересного опыта, создание чего то нового. Это буквально игра".

[Matt-emgm]

"Because safety or something, I don't know" is just a motto of this channel honestly

[KB_-_]

That kid could win the lottery and he would just politely smile and nod. His ability to keep it cool is epic :)
