My personal response to the activity is that it is triggering.  I am a bit too old and do not respond well to glitter.  I have had plenty of opportunity to look at settling sediment and other forms of sorting in the form of sand studies.  Might work for a younger crowd. 

Thanks but NO thanks

I liked the acitivity of the week before, but have decided not to do lots crafty stuff.   

It is an aesthetic that appeals tho.
