looks like my paint rollers, spraying paint all about when cleaning but with much pressure and THAT end result. Can see how they used to cut through rocks & mountains with water pressure.

The wheel got lodged in the ceiling insulation. They recovered it in the followup video:

Reminds me of a TCT router bit that came out of my 3hp table mounted router and cut into & imbeded into a bottom chord of the garage frame. It was at 22,000 rpm. (mid 1970s)

288mph on a longboard...Ok then we're good.

Yeah but the wheel started coming apart way before it blew off. SOOO, you better keep that long board under 100mph.

I remember when we used to make skate boards out of steel roller skate trucks and tow them behind our bikes. Around and round and round the block for hours. When we got done, was difficult to walk as our feet were tingling from the vibrations of the hard wheels on the road.
