Step 2: Diaper Gel
Now most people know that a diaper can hold quite a bit of liquid, but you might be surprised to see how much.
I tried putting over 4 cups of water in this thing, and you can see that in just a few seconds, all the fluid is completely absorbed, without a drop left in the bowl.
To see what's inside, let's go ahead and rip it open, and dump the contents into a bowl.
You can see that if we add a bit more water and mix it together, we've got ourselves an amazing, fiber rich hydrogel.
I tried packing some of this stuff into an airtight bag and freezing it overnight, to make an improvised ice pack that won't leak.
Step 3: Super Soil
One adult sized diaper makes over 12 cups of hydrogel, and the small pieces of cotton wadding break apart and mix right in.
Now we're going to need some all purpose potting soil that you can get at any home improvement store, and a large mixing bowl to dump it in.
Add equal parts of dirt and gel, then begin working the two together until they're thoroughly mixed.
Now you've not got a super absorbent, super soil that's light and fluffy, and perfect for your potted plants.
