I saw this on Skip to My Lou and knew it would be perfect for an activity with Maggie. We made them in a Jell-o Bean mold, or you can use candy molds or probably even silicone ice cube molds.
1 3 oz box flavored gelatin
2 packages unflavored gelatin
1/3 c. water
Sprinkle the gelatin over the water in a small saucepan. Let sit 5-10 minutes. Heat over medium heat and stir until dissolved, 2-5 minutes. Pour into your molds (I used a plastic measuring cup with a spout) and let cool for 20 minutes. Pop out and eat!
They came out really easily, but were super sticky to themselves, our fingers... pretty much everything except the mold. So I did dust them with a bit of cornstarch.
Update: I made these again using fruit juice. I used 1/2 c. fruit juice and 3 1 oz packages of unflavored gelatin. I used apple juice, so they were kind of gross, but I think pineapple or a red juice would be yummy. They were not as sticky as the jell-o ones.
I made them in a rubber ice cube tray from the dollar store! They came out great once they cooled enough.
