As always we’re sponsors by I saw a demo of this mad contraption, and I just had to buy one - it’s a spinning LED fan. It’s completely mad.

We’ll try it out and then take it apart to see what makes it tick. It’s actually really cool.

It’s amazing what you can do with persistence of vision. The camera really doesn’t do this justice.

I got mine off AliExpress from here (affiliate link): but there are plenty of others available. Just search for “LED fan” on AliExpress.
