Halloween Open Day
From London Hackspace Wiki
The London Hackspace is a non-profit, community-run hacker space in central London. We provide a space where people who make things can come to share tools and knowledge.
On November 2nd we'll be opening our doors for a special Hallowe'en open day. Expect dry ice, UV lights, mad science, and much more.
We'll have a bar serving beer and soft drinks to raise money.
Facebook event, if you're so inclined.
