Does anybody know where I can get a big perspex prism to show lasers through.
30cm wide by about 20cm deep.
A student borrowed mine for Art,filled it full of water and then dropped it.
Needless to say it broke!

The glue for perspex is chloroform, if you haven't thrown it yet

Thanks but it is beyond fixing. I wonder what everybody else uses?
