Needles with an engine?

I’ve been looking for a nice pattern to knit for myself (rather than all the baby stuff I’ve been doing so far) and I keep finding patterns that have been knit on Speed Stix.

Anyone got an idea what these are?

If I’m right, and they do have an engine - what are they powered by :yay:

Speed Stix are, as far as Lion Brand defines them are size US 50 :shock: They are like knitting with logs but they sure are FAST!!!

And you would use 2, 3, or 4 strands of yarn knit together. They get about 1st/inch so wouldn’t take much time to knit something.
