Soft fruit like seedless grapes, strawberries, pineapples, melons
Plain yogurt for dipping (optional)
Skewers/Popsicle sticks/Firm Straws
Alternate between the fruit and cheese cubes and slide on the skewers, popsicle sticks or firm straws. The plain yogurt would make a nice dipping sauce to dip the skewers into.
Leaders could put the items on the skewers for participants or let participants put them on (make sure they wash their hands first).
Tip: Popsicle sticks or firm straws may be better for younger children
