My parents came to visit last week and brought a fun treat for the kids. This was actually an idea I got from a friend, who suggested a kid version after a night of Lava Lamps (something like this). It couldn't be easier, and it got rave reviews from my kids, my parents, and myself.
- Make your favorite flavor of gelatin (Jell-O, or homemade with Knox and fruit juice), in the thicker "Jiggler" recipe.
- Once set, cut into small shapes with a knife or small cookie cutters/aspic cutters. Shapes are fun, but easy squares with a knife are perfectly fine for this, as they'll look like ice cubes.
- Give your kids several gelatin shapes and a cup of your favorite clear carbonated drink. We used 7Up.
- Plop the gelatin pieces in the drink.
