Liquid Sand Hot Tub

Mark Rober fills a hot tub with liquid sand and the result is unbelievable!

Rober a fan of simple, creative design, studied Mechanical Engineering in School.
He worked for NASA JPL for 9 years, 7 of which were working on the Curiosity Rover. His sold his side hustle company ‘Digital Dudz’ to the guys who make Morphsuits in the UK. As part of the sale he quit his job at NASA and worked for them coming up with all their new costume ideas for 2 years.

Recently, he was presented with an opportunity to return to my Engineering roots to come do some ideation type of work for a tech company near San Francisco, lets hope he can manage to still make these hugely popular videos.
