Hello all,

We are hoping to incorporate a temperature sensitive material that  
will change colors when visitors put their hands on it.
I've see thermal hand print paper and film through teacher catalogs,  
but am concerned about the longevity and replenishment of it in an  
exhibit setting.
There is also a glass heat sensitive tile through a company called  
Moving Color. Unfortunately from my testing, it needs to be submerged  
in water to change colors. It will change colors with the heat from  
your hand, but it has to be touched from the back side. Again, not  
conducive to mounting to a wall.

Any suggestions are much appreciated.

Many thanks,
Sheri
