Update - Realized I had On Demand access to previous episodes. So I saw the first episode. The info said "Kevin and Grant push the physics of flight to build an extreme trash can rocket"
GRANT? Grant Imahara? Formerly of Mythbusters?
Uh, no, some other guy named Grant.
So far, it does not seem bad, just not great. I think worth checking out more, unless you just do not find it to be your cup of tea.
Using a 5 star rating, with Mythbusters being 5, and Rocket City Rednecks being zero, I'd give it 2.5 to 3. Subject to change with viewing later episodes… especially the rocket skateboard episode.
Now, the trash can "rocket" was not really rocket powered. It was more like the old trick of using a tin can with firecrackers or cherry bomb inside, so the explosion blows the can vertically into the air. o, they tested with homemade huge Cherry bombs, and other tricks to make an explosion go off inside to fling the unpowered trash can into the air. Including pouring some liquid nitrogen into a large plastic bottle, so when the nitrogen boil-off overpressurized the bootle, the "boom" had a result (won't say what as it'd be a spoiler)
The cans had fins and "nose cone" (aluminum bowl) attached so they flew stably…. when they flew.
