FREE ENGLISH SPEAKING CLASSES for all members of my website (www.skype-lessons.com). This was recorded on Zoom this morning, but I promise to use a Nostr based program in future (e.g. HiveTalk). I have to get my students used to HiveTalk first, and usually, there are problems when switching to a new platform. I will probably use HiveTalk Vanilla, as I know this is the easiest version to use.

PREPOSITIONS of SPACE and TIME (Pre-Intermediate Level). 8000 zaps for lifetime access to this lecture + 13.5 hours of other lectures + 40 quizzes. Zap this note 10000 sats, and I will even include a 30-minute live class on Hive Talk. More info: https://www.skype-lessons.com/courses/master-english-pre-intermediate

Plasma propulsion with Macka B in the background. Needs a little shake to get started. At full vacuum, there aren't enough ions to push it round; nevertheless, a Nostrian student mentioned 'reactionless thrust' a few months ago, something that I used to be really interested in, so I plan to put an old electrostatic motor in a vacuum chamber to see if 'reactionless thrust' is still science fiction.
