Yes, it genuinely took 3 weeks of trial and error as getting the ice as clear as possible was a big issue. The molds were just simple tupperware boxes.
We tried various techniques - doing it thin layer by thin layer, putting the card in with the water and hoping it freezes properly and clearly. They all went wrong in that every time we took the blocks out of the freezer, they would crack. In the end we did two half molds and put the card in a sandwich configuration. We then crushed up ice and filled in the gaps. It worked well, but wasnt as clear as I wanted it to be. To get it as clear as we could, we were boiling water, using pure water, de-ionised water etc.
Not recommended unless you have a TV company giving you a good budget and 500,000 viewers!!
