So the "excitement" of Berzelius Day is over - posting 24 short videos of chemical reactions in 24 hours.
It was a fun day for my chemistry channel - periodicvideos.
But life moves on and other channels need tending to.
Three new videos have popped up today and I thought I'd share them here.
First, here's a new video for the occasional series My Favourite Scientist.
In an unusual choice, it features the fictional scientist Mr Spock!
A new Numberphile video has been uploaded - here we have a card trick with a numbery streak.
And finally Deep Sky Videos is continuing its journey through the Messier Catalogue with a new video on M76 - the Little Dumbbell Nebula.
