@chai2,
You clearly don't have any idea who Simone Giertz is and what her channel's ... modus operandi/raison d'etre.
She gets people interested in engineering (and science through engineering) by making crappy robots. Learning through engineering failures and experimentation.
One of her more notable other jobs is helping Adam Savage of MythBusters fame on his Youtube channel, Tested (similar geek related subjects and flights of fancy).
Even without any context, did you think anyone would possibly invent this contraption for mass production and sales? I hope not. This has far better production value and far less painful earnesty than informercials.
