2 (3 oz) packs of Jell-O (Raspberry and/or Black Cherry)
1 pkg unflavored gelatin (for extra firmness)
3 cups boiling water
15 drops green food coloring
100 flexible straws (or enough to fill your container)
Tall container (1 quart or 1 liter carton of milk)
*Option- 3/4 cup whipping cream (To make the lighter and more opaque tail of the worm)
1) Combine gelatin in bowl and add boiling water.
2) If you are making the light portion, let it cool to lukewarm then separate the Jell-O into two (2) containers and only add cream to one of them. You may not need to add the entire amount of whipping cream; just add a little, stir and check until you have achieved the desired color.
3) Add the 15 drops green food coloring to both the plain gelatin and cream/gelatin mixture.
4) Gather your straws and don’t forget to pull on the bending part so it is fully flexed.
5) Important note! The straws have to fit together tightly so the Jell-O stays in the straws. For this reason, a smaller 1 liter carton may be better to ensure you will get worms of a good length.
If you have a bigger container, be sure to put something around the straws, like a rubber band, to keep them tight together. Or you could just add more straws to fill the container.
6) Add the gelatin mixture to the straw-filled container and let it set until firm.
If you are making worms with the lighter tail, be sure to add the gelatin/whipped cream mixture to the straws first, filling the straws about halfway then following with the plain gelatin. If you do this step in reverse and add the plain gelatin first, the cream/gelatin will try to sink to the bottom of the worm and you will lose the two color effect.
Freeing the worms
There are multiple ways you can remove the worms from the straws. You can roll a rolling pin over the straws and squeeze them out or you can hold the straws over warm water. The worms will slip right out.
