I Built a Cardboard Submarine

[Weisz]

I expected total sinkage.
I was not disappointed.
10/10 video, great job!

[jonsan]

Liam's videos in 10 years: I'm going to be building a working rocketship out of cardboard ladies and gents.

Liam is like the person to make our terrible childhood ideas actually work

[CookieCa]

This is probably one of the coolest sponsors anyone has gotten ever

I can't be the only one who found this channel one day then watched every single vid.

Awesome channel man, thanks for inspiring me to do some projects of my own.

I was genuinely scared at one point that he wasn’t gonna be able to get out and the fact that nobody stopped him from doing this is mildly concerning. 😂

[charlottenew]

The amount of anxiety I experienced while I imagined Liam trying to break out of the submarine to get out is very very high😂

6:48 the titan submersible inplosion recreation:

[achromaticCacophony]

a tip from someone who won a cardboard boat competition: cover the entire thing in duct tape. duct tape is water proof, cardboard is not

[eggofilms]

One day there will be a Netflix documentary about Liam and his creations
*”Inside the mind of a genius”*
Reviews: *Epic*

[jupama.]

Anyone else got this recommended after the submarine incident

[dodololo]

Liam is a great inventor, he should be put in the Guinness book of world records for being the best YouTuber.

Liam:
1)builds a card board submarine,
2) gets an EPIC sponsor,
3) has a hat that says polo when he said yolo and
4) almost drowns
Also Liam:
"that sounds like a great opportunity to wear a suit"

[isabelxo]

liam: getting inside a box and then going under water is a terrible idea…
also liam: continues to get inside a box and go underwater 😌👌

“I loved you like a son” .. his poor.. poor children

[shrimpychicken]

Liam should become a rocket scientist so that we can get more nonsense but high-tech

[glcywvw]

Can we just acknowledge the fact that: Liam never clickbaits

[Almuso]

Nice, you truly are the definition of “so bad, it’s good!” As an Australian, I can say Your amazing Liam!

[doylethechocolatelab]

Liam's chuckle after he opened the Stanley knife was concerning

[mrmistermelom]

This guy literally brings our childhood dreams to life
