I've posted two videos for this year's Halloween.
At the time of posting a YouTube glitch meant they'd not been delivered to YouTube subscribers... not ideal.
But anyway, here they are:
Neil's fiery cauldron - liquid oxygen and red-hot charcoal
Vampire numbers and a counting obsession
HALLOWEEN PLAYLIST OF SCIENCEY VIDEOS
I also uploaded this video today about the Ash Dieback problem gripping the UK.
The video has also went missing in action on the YouTube subscriber feeds.
UPDATE: The YouTube technical boffins have 'fessed up that their subscription system messed up for several hours... I was unlucky to be affected three times... It's now fixed but the videos will feed in lower on the subscription feeds! :(
