What do you get if you cross inline skates, an angle grinder and a bag full of 12 volt batteries? Nope, not the props for a fetish night, but a pair of Go-llerblades.
These incredibly dangerous motorized skates, from Instructables member "Stasterisk", make the Chinese Death Skates look pedestrian. The angle grinder is gaffer-taped to one skate and the grinding blade replaced with a wire brush. Five 12 volt batteries provide the power, and the on switch is taped down to go. The brush spins and off you go.
The MkII version actually has an off switch. Previously Stasterisk said that
Don't try this at home.
