Candy Aquariums are easy and fun to make. All you need is a few simple ingredients: Candy ( of your choosing) Mason jars Jello For the fish aquarium I used jelly beans and some swedish fish. See the difficulty with this one is going to be trying to make them without eating all the candy. For the boys, I got some chocolate covered raisins and some gummy worms. I used raisins to line the bottom of the jar to create the dirt. I let the lime jello sit in the refrigerator for about a half an hour, before I began pouring the jello into the jars. Now, i am going to add the fish. And there you have it. It’s simple, easy to make, and you've got a fish aquarium. If the fish start going the wrong way, i just recommend taking a fork and pushing them the right way. w This was a new discover i found this mixchief jello and it’s basically clear jello and you can add any flavor soda that you want. So we added some diet coke soda to help create a dirt effect. I let the jello sit for about a half an hour as well. Next, pour it into the jar. I a actually put the worms in as I went long.
