Startup founders could spend a lifetime building products without validating 🤦‍♂️

That ladder is a million-dollar idea!

my god lol. Some of these were the most elaborate contraptions I've seen in a while 😅

Amazing! At least most of those seem like doable in an afternoon or at most in a few days by a single person, definitely not stuff that takes years and teams of multiple people to build.

Thumbs up to the teamwork they have for these videos

Now all it needs is dark mode

I am one of them!!

Inventions of the century that nobody want!🤣

IDK that ladder looks marketable.

Ahahah this is hilarious

thanks bro 😂
