I made this snack for our lesson about when Jesus calmed the storm. The small cups with lids came from Walmart in a package of twenty. I made five or six small packages of blue Jello and evenly distributed it between the cups, then put them in the fridge to set up. (Just follow the package directions.)
At serving time, each of the kids got some Sour Patch Kids to represent Jesus and his disciples, and stuck them in the water. I’m not a big fan of Sour Patch Kids, but they actually tasted pretty good when they had been sitting in the jello for a little while.
