GoldenrodPaper

=Goldenrod Paper Demo=

Goldenrod paper is yellow paper that is sensitive to pH! Compared to pH paper, it is very cheap. Wiping the paper with a basic solution makes it turn red. Wiping the red areas with an acidic solution makes it turn back to yellow. This is a great way to tie chemistry to the Wood and Paper kit. Secret messages can be written on the yellow paper with wax. A basic solution will make the message appear and then an acidic solution will make it disappear again.

Here is a better explanation of the demo and a place to order it: []

There is some goldenrod paper stored in the GK12 storage room.
