I made the homemade snow and used it at my winter olympics activity morning. The residents liked feeling the snow saying it had been a long time since they had felt any, and a few were glad it wasn't ice cold like real snow.
I was wondering how long I can keep it, does it have a use by date, or do I have to remake it every time I want it?

I do this activity every week. We had a list provided by someone, but now the residents are providing the words themselves. Once we are finished the residents look at all the words on the board and try to guess how many words they found. The person who gets the closest gets a prize.
