This is a ministry we've been doing over a year now every Friday (after summer) there is school and weather permitted. Completely free to the students. Yes, we do except donations. Donations can include but not limited to ice, sno-cone syrup, cups, spoons and also monetary donations. 
Our Pastor started this ministry when he noticed all the kids walking home from school and wanted to give them a cool treat for the hot weather. 
On any given Friday, we have given out 40-60 sno-cones to students. We start at 3pm every Friday til 4pm unless we run out of product or energy (🤣), whichever comes first.
