A quick idea... for children fun. Grind some mint leaves, and make ice cubes with them to flavour drinks. Teach the children to recognize the mint plant, pick leaves and get them to cut or grind the leaves and make the ice. If you don't want to use scissors or knives, have them cut up the leaves in tiny bits by hand (like you do with fresh basil). You can also put a whole leaf inside each cube. Ice takes about 7 hours to make, so do it the day before you need them... and see that you invite them to a minty drink the next day!
