>>5479110I really want to do this with one of those small all enclosed fish tanks.
>>5481261put them in water. It may take a few days for them to reach full size. Also, its really really easy to underestimate how much they're going to expand. A teaspoon's worth filled a quart size jar. Its easier to add a pinch, let it grow, and add another pinch until satisfied than to put a bunch in and have them explode everywhere as they grow. They are bouncy fuckers, they are slippery, and they are super clear and hard to spot on your bathroom/kitchen floor.
