Making Holograms

Today we tried to make 3D holograms and to be honest it was a bit of a disaster. The CD cases were really difficult to cut and if you didn't have them cut perfectly to size they tended not to go together so well.

Oh well. That is the art of experimenting. Sometimes you just don't realise what works and what doesn't until you give it a try. We will revisit this at some stage this year and get it right!
