really clever and works brilliantly - I had to adjust the green colour slightly for myprojector and filters so best to check it before you use it. It actually had my top set yr 8s bamboozled for a few minutes so worth a try for all levels! Thanks for sharing Alessio.

Great super for year 8 worked beautifully with ordinary filters and one eye shut!

Great, my students really enjoyed it. I didn't make the glasses instead I gave them filters.
