We actually did this experiment twice, as the results were not what we expected…

After one week, here are the two apple slices. The first one is the “mummified’ apple. The second is one we just left out. The second one looks truer to color! The mummified apple has retained its shape, but the peel has turned black, and the insides discolored. I thought maybe it was because I soaked it in salt water before hand.

So we tried again! We did the same thing, without the salt water soak. Here is our apple slice weighing in at 7/8 oz.

And here’s that same apple almost a week later, weighing in at 1/4 oz. It has lost 5/8 oz due to the dehyrdation of the salt/baking soda mix.

But it still looks black. I think we should have given it a month to see moredecay on the untouched apple slice.
