Step 2: Materials...

Picture of Materials...
OK this was easy for me...

I used an old posterboard that wasn't fit for demonstrations any more, it's foamcore with a few bits of velcro on the back, since this was vaguely experimental looks weren't too important...

Glue I used something called Hi-Tack Fabric Glue, which has a million uses, wood glue, hot glue, any tacky and strong glue should do, don't bother with superglue it'll melt your foam and not stick the mirror...
